So
Now multiply both sides by and you are there.
I have been having trouble trying to follow along an example of, finding the derivative of .
Using the property
Now differentiate the left side, then the right side....
Left Side:
Right side:
multiply both sides by f(x) , to get f'(x) by itself.
Now replcace f(x) for
I getting confused at this part...... how does it get to here
