**Reiny**, Friday, October 28, 2011 at 12:04amYou should have a list handy for the basic trig function derivatives

so if y = (csc x)^7 -cos 4x

dy/dx = 7(csc x)^6 ( -csc x)(cotx) + 4sin(4x)

etc

**hannah**, Friday, October 28, 2011 at 12:15amThanks. My teacher told us we need to use the chain rule in these problems, and i'm having trouble figuring out when and where to use it.

**Reiny**, Friday, October 28, 2011 at 12:38amI did use the chain rule in finding the derivative of

(csc x)^7

**hannah**, Friday, October 28, 2011 at 12:50amI know. I just realized that I messed up what goes where when I was doing it myself. My problem is applying it to other problems, esp when i also have to use the quotient or product rule.
