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
