I have to write an autobiographical research paper on race in my community. 1. The paper must have an introduction & thesis statement. 2. Body supporting evidence and in text citations. 3. conclusion. 4. three references. I am totally lost and don't know...

z=cos(4 theta) what is the derivative. I know that the derivative of cos is -sin, but what do i do with the 4 theta. does that just become 4?

Could someone please check my work on the following problems? I want to be sure that I'm doing them correctly; i'm just required to find the derivatives and then simplify. g(t)= t/sint g'(t)=1*sint-cost*t/(sint)^2 g'(t)=sint-cost*t/(sint)^2 y=ln(e^ax) y'=...
