# Sketching a Gradient Function

 2 Sketching a Gradient Function Given a graph of a function, sketch a graph of the 'gradient' function. Key Concepts: Gradient zero at stationary point ( Maximum or Minimum, Where a function is increasing, decreasing, stationary Demo of Gradient Function (enable macros) Introduction to differentiation and motion graphs link to www.mathsroom.co.uk Calculus surfer - Thanks to Evelyn Knight for sourcing the link (homepages.gac.edu) Note: you need to remember to use * for anything multiplied, e.g. y = x*(x+1)*(x+2).
