You will struggle using this approach I think. Read section 3 and 4 here: http://www.mash.dept.shef.ac.uk/Reso...b-logs-exp.pdf
i am trying to find the derivative of a^x using the limit definition of the derivative.
in order to find the derivative of a^x i need to show:
lim (a^h - 1) / h = ln(a)
h~>0
i can't see any obvious way to manipulate the expression so that i get ln a in the end. please help.
