Hey guys... here is the problem g(x) = sqrt(sin x)

I am unsure how to do this.. I think the answer is 1/2 sin/sqrt(sin x)
 
sqrt(sin x) = (sin x)^(1/2)

Recall the dervaitive of sin is cos. Now it's the chain rule all the way.
 
Come on, you're so close! Besides, integrating is more difficult than differentiating.
 
Can you take the suggestion you were given? You got all but one piece.

(x)soc*[((x)nis)trqs\(x)nis*(2\1)]
 
You said you wanted to work backwards.

(d/dx)(sin(x)) = cos(x)

We're working really hard to try to get you to show a little self-confidence. It is very difficult to get a student who just wants the answer to respond to appropriate leading questions. Our purpose is not to do your homework for you. You have to do it. When we ask you a question, answer it. When we tell you that you are really close, you are really close. When I give you the piece you are missing, as I did in this post, use it. If you are not willing to try to learn to do it on your own, you will have a problem with me. It wouldn't be the first time.
 
Sorry sir. but anyways giving me the final answer will help me work towards getting the right one. I dunno about you but the answer alone does nothing for me anyways since as in every math class I have ever taken you need to show your work into how u got there anyways.
 
You were one step off. unco gave you the methodology. I gave you the answer. It's a bit tough to tell what you might need in addition to what you have.
