This document discusses techniques for finding derivatives of basic functions. It covers finding the derivative of constant functions, which is always 0. It also discusses the derivatives of identity functions (f(x)=x), which is 1, power functions (f(x)=xn), which is nxn-1, square root functions (f(x)=√x), which is 1/2√x, and exponential functions (f(x)=ex), which is ex. Examples are provided for each case along with exercises for students to practice finding derivatives of various functions using the appropriate technique.
