Question

How can I solve integral of 2sin(t/2)dt?

Answer 1

put u=t/2
du=1/2 dt

the integral becomes
integral 2 sin u 1/2 du = integral sin u du

Answer 2

Are you looking for
\[\int\limits_{} 2\sin(t/2) dt\]?

Answer 3

yes

Answer 4

This 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.

Answer 5

I just solved, and it is -4cos(t/2)+c. But I used u substitution.

Answer 6

Where did 4 come from ?

Answer 7

when ask my question before, you forget to multiply du by 2. I think you divided by 2 instead of multiply.

Answer 8

ya u r right ..sorry for that

Answer 9

ok :)
