WebVector, Matrix, and Tensor Derivatives Erik Learned-Miller The purpose of this document is to help you learn to take derivatives of vectors, matrices, and higher order tensors (arrays with three dimensions or more), and to help you take derivatives with respect to vectors, matrices, and higher order tensors. 1 Simplify, simplify, simplify WebSuppose you've got a function f (x) (and its derivative) in mind and you want to find the derivative of the function g (x) = 2f (x). By the definition of a derivative this is the limit as h goes to 0 of: Which is just 2 times f' (x) (again, by definition). The principle is known as the linearity of the derivative. Webe^x times 1. f' (x)= e^ x : this proves that the derivative (general slope formula) of f (x)= e^x is e^x, which is the function itself. In other words, for every point on the graph of f (x)=e^x, the slope of the tangent is equal to the y-value of tangent point. So if y= 2, slope will be 2. if y= 2.12345, slope will be 2.12345. church of christ senior living centers
