Develop and C-Code that numerically integrates the following function, integrate using
TRAPEZOIDAL rule.
Solution
#include
#include
double f(double x);
void main()
{ int i,n;
double x0,xn,h,I;
printf("enter value of x0,xn");
scanf("%lf%lf",&x0,&xn);
printf("enter the value of h");
scanf("%lf",&h);
n=(xn-x0)/h;
I=f(x0)+f(xn);
for(i=0;i= 0 && x <=5)
{
return (pow(x,3)-0.23x+30.67);
}
else
{
return(pow(e,7x)*cos(0.3 *pi*x));
}
}
