LoudBimmer Posted March 10, 2012 Report Share Posted March 10, 2012 (edited) Here's the problem: y=2^sin π x and I need to find derivative of it. Here's the derivative: (2^sin π x)(π ln2)(cosπ x) My question is, Why do I need to have π in front of ln2. π is pi Edited March 10, 2012 by LoudBimmer Quote Link to comment Share on other sites More sharing options...
LoudBimmer Posted March 11, 2012 Author Report Share Posted March 11, 2012 any math majors? I'm assuming pi comes when I take a derivative of pi x in the end, but why would it be in front of ln. Quote Link to comment Share on other sites More sharing options...

blownengine Posted March 11, 2012 Report Share Posted March 11, 2012 (edited) The sad thing is that I am in calc 2, my final is monday, and I can't answer that question. haha. I think it's because pi is a constant multiplier of x so you can bring it out front, but I could be wrong.

LoudBimmer Posted March 11, 2012 Author Report Share Posted March 11, 2012 Simple chain rule here. I got a test monday, so need to figure this out before. Since It's a sin(pix), after taking derivative of sin, which is cos, I would need to take a deriv. of the inside, pix, which would be pi, but after simplifying it, it should be in front of equation.
