hi i need to do an integral in ++ but i need all the values ​​to be positive, i do not want negative integrals help!!

Question

help me?

Answer 1

Simply create the program to take all the values and when doing integration, perform a check to validate all the values to be positive only.
Even if you fail, we help you out, but TRY FIRST.

Answer 2

in a few words I need to solve integrals and return absolute value to me

Answer 3

ok thanks bro let me see

Answer 4

In programming or in mathematics?

Answer 5

Please elaborate your question!

Answer 6

I thought of some series like simpson's and calculate n numbers of rectangles under the curve

Answer 7

#include<stdio.h>
#include<stdlib.h>
#include<math.h>

int main(void){

int i,N;
float a,b,h;
float integral=0.0;

N=10;
a=0.0;
b=1.57079632679490; // = pi/2

h=(b-a)/N;

for (i = 0; i < N; ++i)
{
integral = integral + h*sin(a+h*i+h/2.0);
}

printf ("La integral de senx en el intervalo es %f \n", integral);

system ("pause");

return 0;

}
then brother what I'm looking for is to implement integrals with different intervals, and that their values ​​are absolute, this is a simple idea and only calculates the integral of sen .. :o
