What is Monotonic function?
In [[algebra]], a '''montonic function''' is any function whose [[gradient]] never changes sign. In simple words, it is a function which is either always increasing or decreasing. For example, ''sin x=f(x)'' isn't a monotonous function or simply, non monotonous function. That is to say there are no [[turning point]]s but there may be [[stationary point]]s where the gradient is momentarily [[zero]]. The [[Derivative (mathematics)|derivative function]] of a monotonic function which describes its gradient will never change sign. <ref> [http://mathworld.wolfram.com/MonotonicFunction.html Monotonic Function] Mathworld , Wolfram alpha , Accessed March 2017</ref> ==References== {{reflist}} {{stub}} [[Category:Algebra]] [[Category:Functions and mappings]]
