# Area under a curve

Posted on 1997-08-05

Area of a region under the curve can be described by taking the integral of the function, given the limits of the curve. My problem is to write a program in C, using "Functions" to calculate the area of the region under the curve. The formula/equation to be used to solve is:

Area=Delta*[ {f(a)/2} + {f(a+delta)} + {f(a+2*delta)} + {f(a+3*delta)} + ............. + {f(a+(n-1)*delta)} + {f(b)/2} ] , where delta=((b-a)/n), a=(-1.0) and b=(1.0) and are REAL.

The equation of the curved line is given by:

y = e^ ((-x^2)/2)

Your quick response will be greatly appreciated. Thank you very much.

Sincerely,

Abdul
