1. The problem statement, all variables and given/known data Create a program that computes for the value of sine function. Then compute for its integral from 0 to pi with N intervals, where N=4,8,16,256 and 1024 and compare the result for the trapezoid and simpson method. 2. Relevant equations Trapezoid rule of Integration is (b-a)((f(a)+(f(b))/2) 3. The attempt at a solution here is the code I made but I'm getting "Unclassifiable statement" at the i1 equation. Is there something wrong with my code? We are using fortran 90 I'm trying the trapezoid rule 1st.
