We want the derivative of

Take the derivative of the outside:

Take the derivative of the inside:

Now, multiply them:

Simplify and make it 'purdy':

See there?. Now you try it with, say, and show me what you get. - Jan 4th 2009, 03:52 PMskeeter

Math Centre (www.mathcentre.ac.uk) explains it in a clear manner too, includes examples and problems to try out. See their Chain Rule Booklet: http://www.mathcentre.ac.uk/resource...-chain-feb.pdf
