Right, right. That rule would make those very easy! Thanks bud! :-p I am still having trouble with the cosine one however. I apparently need to use multiple steps to find the derivative.

Ok good! That is what I thought. You have been so helpful! Thanks! I have a couple more [shorter] questions, however don't feel obliged to respond if you don't want to... 1. Find dy/dx of y = x^5 * 7^x 2. Find dy/dx of y = (1/2) ^ x 3. Find dy/dx of y = (cosx) ^ x

Thanks so much! Does that simplify any farther?

Ok, right. So 2x = ln (sin(x+3y)) Then if you take the derivative... 2 = (1/sin(x+3y)) * cos (x+3y) * 3 * dy/dx So dy/dx = 2(sin(x+3y))/ 3(cos(x+3y)) ? Is that right?

I need help with this problem. Find dy/dx if e^2x = sin(x+3y) Any help would be great! I began by taking the natural log of both sides...which may not be correct?? Thanks!
