Calculus is a branch of Mathematics which deals with the methods of Derivation and Integration. These two

methods are the sub-branches of Calculus and are used to solve functions based on them. AP Calculus is

the Advanced Placement Examination in Calculus which is given in order to test a high school student in

Calculus questions.



Example 1: Find the derivative of the given function, f(x) = x5 + 2x3


Power rule of the Derivatives -> d f(xn)/dx = n*xn-1

Given function: x5 + 2x3

Applying the above formula for every term of the function, we get

Derivative of the given function -> d f(x)/dx= d (x5)/dx +2*d(x3)/dx

df(x)/dx = 5 *x5-1 + 2 * 3 * x3-1

d f(x)/dx = 5x4 + 6x2

Hence the derivative of the function f(x) =x5 + 2x3 is 5x4 + 6x2


 
Example 2: Calculate the definite integral value of the function, f(x) = 4x3 - 3x2 and ‘x’ ranging from

0 to 2.



 ∫xn dx= x(n+1)/ (n+1)

Apply the above formula for the given function, we get

∫(fx) dx = 4 *x3+1/(3 + 1) –3 *x2+1/(2 + 1)

∫f(x)dx = x4 –x3

First substitute x = 0 and x= 2 in the above answer.

When x= 0, ∫f(x) dx= 04 – 03 = 0

When x=2, ∫f(x)dx= 24– 23 = 8

Now subtract 8 - 0 = 8

Hence the definite integral of the given f(x) is 8.
