Best ResponseYou've already chosen the best response.0This one is easy, really. Can you figure out the antiderivative? The antiderivative of sin is what? And the antiderivative then of t/2 is what? You would be using the chain rule to differentiate to get this function.

Best ResponseYou've already chosen the best response.0when ask my question before, you forget to multiply du by 2. I think you divided by 2 instead of multiply.
