1. The problem statement, all variables and given/known data Let's take two problems, the derivative of 2x and xπ For the second one the book says that answer is πxπ-1 Well if you can do that for the above, then why not for the first problem? The book gives the answer to the first problem as 2x ln 2 why not x2x-1? essentially what i need to know for finding derivatives, there are two techniques. 1. nx^n-1 2. k^x ln k when do I use which technique?
