WebThe derivative is an important tool in calculus that represents an infinitesimal change in a function with respect to one of its variables. Given a function f (x) f ( x), there are many ways to denote the derivative of f f with respect to x x. The most common ways are df dx d f d x and f ′(x) f ′ ( x). http://www.gatsby.ucl.ac.uk/teaching/courses/sntn/sntn-2024/resources/Matrix_derivatives_cribsheet.pdf
