one of the applications of computers in numerical analysis is computing the area under a curve. one method of calculating the area under acurve is to divide the area int a number of trapezooids of same width and summing up the area of individual trapezoid. the area of trapezoids is given by 0.5*(h1+h2)*b. write a cprogram to calculate the area of a curve of the function f(x)=x2+1,between two points.
