Make a new question close this one and put a question that you would like to learn how to solve and you will have people explain it to you

This website is a great resource for (almost) any math level. http://tutorial.math.lamar.edu/Classes/CalcIII/ChainRule.aspx

Perhaps a picture would also help. Suppose you have a function $z=f(x, y),\;\; x=g(s, t), \;\;y=h(s, t)$. Draw a diagram like so.|dw:1334457822152:dw|
