Question

Help? [:
evaluate the integral from -pi to pi of f(x)dx, where
f(x)= { 4x^4, -pi≤x<0
{ 9sin(x), 0≤x≤pi

Answer 1

You'll need to break the function apart at the boundaries. Evaluate the integral of 4x^4 from -pi to 0 and add that to the value of the integral of 9sin(x) from 0 to pi

Answer 2

Thanks! (; I subtracted them.. Silly me!
