Hi

I need to write a rule for the derivative of where a is a constant. I was thinking of but my teacher said that is not what he is looking for. By the way i cant seem to get it to put the entire exponent up which is (x-1).

Any ideas?

The derivative of will always be

The way to get the entire exponent is to put it in curly brackets: {x-1} - Mar 17th 2008, 06:55 PMo_O
Seems like your teacher is asking you to prove it?

Note that:

If you know that and know how to use the chain rule, then you should be able to find the derivative of
