State and prove Maclaurin's theorem
Answers
Answer:
Maclaurin's theorem is: The Taylor's theorem provides a way of determining those values of x for which the Taylor series of a function f converges to f(x). ... Maclaurin series are a type of series expansion in which all terms are nonnegative integer powers of the variable.

Answer:
The Maclaurin series is a special case of the Taylor series for a continuous function at x = 0 . It is a summation of all the derivatives of a function at x = 0, and gives an approximation of the function for points close to the origin. It is generally a very close representation to the original function. It might possibly be used in engineering, statistics, physics, or actuarial work, though the Taylor series is more likely to be used.
Step-by-step explanation:
A function f(x) can be expanded in ascending power of x like
f(x) = f(0) + x/1! f'(0) + x^2/2! f''(0) + … + x^n /n! f^n (0)
Where,
f(0) = value of function at x=0
f'(0) = value of first derivative of f(x) at x= 0
f''(0) =value of second derivative of f(x) at x= 0
f^n (0) = value of nth derivative of f(x) at x= 0
Proof→
Let f(x) = A0 + A1x + A2X^2 + … An X^n
Where, A0, A1, A2, …An = constant
Consider the function of the form
Using , the given equation function becomes
Now taking the derivatives of the given function and using $$x = 0$$, we have
Now using Maclaurin’s series expansion function, we have
Putting the values in the above series, we have
