Question

I'm not sure how the book changed the limits of integration from -1/2 to 1/2 to 0 to 1/2.How do you do it can someone show me?
here is the problem
it goes from -1/2 to 1/2 and the function is (9-6y^2+y^4)-(4+4y^2+y^4)dy

Answer 1

can't you just subtract?

Answer 2

the whole thing, unless i am reading it wrong, is \(\int(5-10y^2)dy\)
