Area Under Curve

Write a program to find the area under the curve y = f(x) between x = a and x = b, integrate y = f(x) between the limits of a and b.
The area under a curve between two points can be found by doing a definite integral between the two points.

The Prototype of the Function is :

double getAreaUnderCurve (struct Term* equation, int noOfTerms, int limit1,int limit2)

• Where equation represents number of Term in a equation with x_pow and coeff of X
• Where noOfTerms is the number of terms in the equation
• Where limit1 and limit2 are the 2 given points to find the area.
• The function getAreaUnderCurve() return the area of type double corrected to 4 decimal places.(eg : 5.2704. )

Example 1

Input :

    Term equation = x + 3(x^2);     int noOfTerms = 2;     int limit1 = 4;     int limit2 = 8;
    where, struct Term* equation => { equation[0].exponent = 1; equation[0].coefficient = 1; equation[1].exponent = 2; equation[1].coefficient = 3; }

Output :

The function getAreaUnderCurve() returns 472.0.

Example 2

Input :

    Term[] equation = x;     int noOfTerms = 1;     int limit1 = 1;     int limit2 = 1;

Output :

The function getAreaUnderCurve() returns 0.0

Example 3

Input :

    Term equation = x;     int noOfTerms = 1;     int limit1 = 2;     int limit2 = 1;

Output :

The function getAreaUnderCurve() returns 1.5
