Can you tell me if I did number 52 right. My final answer was cos*x to the negative 1/2 cosx to the negative 1/2

I don't think that's it. Concentrate on each term individually (write out the steps of the chain rule), then add together your answers at the end.

why can't i just use the trick?

Ashley said...

sin square root of x is that cosx to the -1/2

Ashley said...

and what's on the mem. quiz tomorrow?

Matt Hickman said...

No, because x is to the 1/2 power, not sin.

The quiz is everything from before plus chain rule.

is that adding/subtrating and so forth
