Can anyone tell me the answer,please ?

Question

f(x) = sin(x)-1 -&<x<0
= sin(x/3) 0<=x<&
Draw a flow chart and write a C++ program to numerically integrate function f(x) from -pi to pi
Hint : integrate f(x) =
sigma (i=0 to i=199) f(a+(i.dx)).dx
such that dx = (pi_(-pi))/200

Answer 1

Integrate sin(x)-1 from -& to 0 and sin(x/3) from 0 inclusive to &. Then add the results to get the answer.
