K. Chen (SFU) Review of Simple Matrix Derivatives Oct 30, 2014 6 / 8 WebWe know that the derivative of linear function f(x) = ax + b is equal to a, where a, b are real numbers. For f(x) = x, we have a = 1 and b = 0. Using these facts, we get the derivative of x equal to 1. ... Important Notes on Derivative of x. The derivative of x will be equal to 1. Both the power rule and the first principle can be used to find ...

Case 2. “a” is zero. If the derivative is with respect to ‘x’, then the answer is ‘a’. Another way to look at it is like this. A derivative describes how much something is changing. In the case of ax+b, ‘a’ is the slope of a line. So, as you move ‘x ... ray white lower north shore group - mosman
