hello
you should share your code , but I already can tell where the issues are :
- line 8 : the if statement is not correct , it's not about x , it's about checking that i = 0 or n (start and final integration steps)
- line 9 : should be : sum =sum+f(x)
- line 11 : should be : sum =sum+2*f(x)
- line 13 : to be removed
still what you have to implement in a subfunction to evaluate f(x) from the current x value (from line 7)
