WebThe Sum and Difference Rules. Sid's function difference ( t) = 2 e t − t 2 − 2 t involves a difference of functions of t. There are differentiation laws that allow us to calculate the derivatives of sums and differences of functions. Strangely enough, they're called the Sum Rule and the Difference Rule . WebThis makes it much easier to compute the desired derivatives. 1.2 Removing summation notation While it is certainly possible to compute derivatives directly from Equation 2, people fre-quently make errors when di erentiating expressions that contain summation notation (P) or product notation (Q
WebIn plain (well, plainer) English, the derivative of a composite function is the derivative of the outside function (here that's f(x)) evaluated at the inside function (which is (g(x)) times the derivative of the inside function. We can apply the chain rule to your problem. The first step is to take the derivative of the outside function ...
