**1) Maclaurin Series with definition and examples**

Maclaurin series is like a another form of taylor series.for learn maclaurin's series you have to about taylor series .

**Taylor series defined as,**

In above equation when we put a=0 then it is known as maclaurin series.

In other words we can say we find series at point zero (0) of Taylor series expansion or you can also say we find sum of terms of point at 0.

####
**Definition Maclaurin Series :**

Maclaurin series A special case arises when we take the Taylor series at the point 0. When we do this, we get the Maclaurin series. The Maclaurin series is the Taylor series at the point 0. The formula for the Maclaurin series then is this:

Above equation has value at point zero hence we find series which placed on point zero.

####
**Some Useful Maclaurin series**

All Series Given below is special case hence you can use directly.

therefore series are like :

####
**Natural logarithm :**

The natural logarithm (with base e) has Maclaurin series,

####
**Geometric series :**

####
**Binomial series :**

The binomial series is the power series,

All series above given are special series therefore you can use directly if you have this kind of function in your equation.

####
**Example :**

Find Maclaurin Series Of f(x) = sinx

####
**Solution :**

To find the Maclaurin series for this function, we start the same way. We find the various derivatives of this function and then evaluate them at the point 0. We get these for our derivatives:

Derivative At the point 0,

f(x) = sin x : f(0) = 0

f'(x) = cos x : f'(0) = 1

f(x) = -sin x : f(0) = 0

f'(x) = -cos x : f'(0) = -1

f(x) = sin x : f(0) = 0

Firstly you have to find derivatives after that put x =0 in derivatives .

After all this put equation and put value hence you get the series which is maclaurin series.

### Taylor Series Expansion With Examples

####
**Definition :**

Taylor series is a series expansion of a function about a point. A one-dimensional Taylor series is an expansion of a real function f(x) about a point x=a.

Distant economies change dramatically. Far away populations move their centers. Sometimes, it’s better to focus on what is happening locally. The same may be said for complicated mathematical expressions.

By looking at the localized behavior of a function, we can often gain amazing insights.

This is where the Taylor’s series is really useful. Simply put, the Taylor’s series is a representation of a function that can help us do mathematics.

Uses of the Taylor’s series include analytic derivations and approximations of functions.

If we have a function which we can differentiate, then we can express that function as a Taylor’s series.

The Taylor’s series for any polynomial is the polynomial itself.

The Maclaurin series for 1/1 − x is the geometric series

so the Taylor’s series for 1/x at a = 1 is

By integrating the above Maclaurin series, we find the Maclaurin series for log(1 − x), where log denotes the natural logarithm.

and the corresponding Taylor’s series for log x at a = 1 is

The Taylor’s series for the exponential function ex at a = 0 is

If You Want To Know About Or Clear Your Fundamental Of Taylor’s Series Then Here Totally Explanation Is Available With Example And Also Their Solutions.

####
**Example :**

####
**Solution :**

In this example we have,

If we compare (x-a) = (x-1) then a = 1

Then according to equation find f’ , f’’ and f’’’

Put this values in the Taylor’s series equation.

**Put a = 1 :**

So, After Simplification ,

So, the taylor series is :

### Chain Rule And Implicit Functions

####
**Example:**

if u=x2+y2, x=at2, y=2at, find du/dt.

####
**Solution:**

here,u is a composite function of t.

du/dt = du/dx * dx/dt + du/dy * dy/dt

= 2x * 2at + 2y * 2a

=4atx + 4ay

=4a [t * at2 + 2at]

=4a2t (t2 + 2)

####
**Example:**

if u=x2+y2, x=a cost, y=b sint, find du/dt.

####
**Solution:**

here,u is a composite function of t.

du/dt = du/dx * dx/dt + du/dy *dy/dt

=2x (-asint) + 2y (bcost)

=-2a2 cost sint + 2b2 sint cost

=-a2 sin2t + b2sin2t

=sin2t (b2 – a2)

### Convergence,Divergence Of Sequences And Infinite Series

Convergence,Divergence And Infinite series is explain the neural mechanism of recollection.

####
**Sequences :**

If for each n ∈ N, a number an is assigned, then the numbers a1,a2,……an is said to form a sequence.

That is a sequence is a function from the set N to the set S of numbers

a1,a2,……an .

Here an is called the nth term of the sequence. Thus if f : N -> S is a sequence then we can write

**f(n) = an**

Symbolically, the sequence is denoted by {an}n=1 -> ∞ or simply {an} or ( an ) or < an >. The number of terms of a sequences is always infinite as n ∈ N.

####
**Convergence Of a Sequence :**

To Understand the concept of convergence let us consider the sequence {1⁄3n}={1⁄3 , 1⁄32 , 1⁄33 ,….}. If we take the value of n sufficiently large, the value of 1⁄3n comes close and close to 0. That is as n -> ∞ we have an -> 0. Suppose if we want to find the value of n for which the distance between an = 1⁄3n and 0 will be less than 0.00001.

That is

| an – 0| < 0.00001

| 1⁄3n | < 0.00001

3n > 1000 > 36

n > 6

If we take n > 6 than the distance between 1⁄3n and 0 becomes less than 0.00001.

Hence we say that the sequence {1⁄3n} converges to 0, and 0 is the limit of the sequence and we write

1⁄3n = 0.

On the other hand if we observe the series {2n – 1} = {1,3,5….} then for large value of n, an = 2n-1 increasing and increasing. It never attempts to tend to any fixed value. we say that this sequence is not convergent. Thus we led to the following definitions.

**Convergence Of A Sequence :**

**Definition :**

Convergence is a sequence {an} is said to be converge to a real number l if given Îµ > 0 ÆŽ a positive integer m such that | an – l | < Îµ,

we can write as,

n → ∞ an = l .

####
**Divergence Of a Sequence :**

**Definition :**

Divergence is a sequence {an} is diverge to ∞ if given any real number k > 0 ÆŽ a positive integer m such that an > k for all n ≥ m, and we can write as,

lim n → ∞ an = ∞

### Maxima And Minima By Second Derivative Test.

####
**Definition :**

Maxima and Minima from Calculus. One of the great powers of calculus is in the determination of the maximum or minimum value of a function.

Consider a function u=f(x,y) of two independent variables x,y whose domain is a certain region R in the xy-plane.

**You Can Also Read :**Protective Relay

We say that f(x,y) has a maximum at the point (x0,y0) of its domain R if f(x0,y0) ≥ f(x,y) for all (x,y) in R. such a maximum corresponds to a highest point of the surface S.

We say that f(x,y) has a strict maximum at the point (x0,y0) of its domain R. if actually, f(x0,y0) > f(x,y) for all (x,y) in R that are different from (x0,y0). Thus the greatest value is reach only at a single point.

Similarly, We say that f(x,y) has a minimum at the point (x1,y1) of R if f(x1,y1) < f(x,y) for all (x,y) in R. such a minimum corresponds to a lowest point of the surface S.

Again f(x,y) has a has a strict minimum if f(x1,y1) < f(x,y) for all (x,y) ≠ (x1,y1) in R.

For Example, consider the function u=x2+y2 defined in the closed disc given by x2+y2 < 1.

The function represents the surface of paraboloid lying below the plane u=1. Here the maximum of occur at all the points of the boundary of the circle x2+y2 = 1.

You can also see different plane equations like Normal Line And Tangent Plane.

**u = f(x,y).**
Obtain the first and second order derivatives, such as

**p = fx**

**q = fy**

**r = fxx**

**s = fxy**

**t = fyy**

1)Take fx = 0, fy = 0 and solve them simultaneously to obtain stationary points. LET (x0,y0) , (x1,y1) , …. be the stationary points.

2)Consider the stationary point

**(x0,y0)**.
obtain the values of r , s and t at

**(x0,y0)**.**You May Also Read :**How Thumb Rule Of Magnetic Field Works ?

(a) If rt – s2 > 0 then the extremum values exist.

-> r < 0 the value is maximum.

-> r > 0 the value is minimum.

(b) If rt – s2 < 0 the there is no extremum value exist. thus there is neither maximum nor minimum at (x0,y0) is called a saddle point.

(c) If rt – s2 = 0 then we can’t say about extremum value and further investigation is required.

(3) Follow the same procedure for other stationary points.

### Improper Integral Of Type-1 And Type-2

####
**Improper Integral :**

The definite integral is said to be improper (or singular) integral if one or both limits of integration are infinite and/or if the integrand is unbounded on the interval

If the definite integral is not an improper integral then it is said to be a proper (or regular) interval.

**Type – 1**

1 . Integral With One end Point Is Infinity

1.1 When Upper Limit Is Infinity

Now If f is continuous on an interval [ a , ∞ ) then an improper integral is defined as

If this limit exist, we say that I is convergent; if not, it s divergent

Here If f is nonnegative and continuous then above integral has an important geometrical interpretation. For each value of t>a the definite integral represents the area under the curve y=f(x) over an interval [a,t].

when t -> ∞ this area will approach to the area under the curve y = f(x) over the entire interval [a, +∞ ).

Thus represents the area under the curve y=f(x) over the interval [a, ∞).

####
**Example :**

**Solution :**

### improper integral

####
**1.2 When Lower Limit Is Infinity**

Now if f is continuous on the interval ( -∞ , b) then the improper integral is defined as

If the limit exists, we say that I is convergent: if not, it is divergent.

If f is nonnegative and continuous on (-∞, b ] then this integral, geometrically, represents the area under the curve y=f(x) over the interval (-∞ , b].

**Comparison Test :**

Up To now we were finding sn the partial sum of the series, to test the convergence of the series. But unfortunately , it is not always possible to find the partial sum sn for every series and hence we cannot apply the definitions of convergence or divergence directly. Thus it becomes necessary to formulate other tests for series with all terms positive. Using these tests we can discuss the convergence of several standard series.

The following theorems gives different tests of comparison.

**Limit comparison test :**a method of testing for the convergence of an infinite series.

**Direct comparison test :**a way of deducing the convergence or divergence of an infinite series or an improper integral
