just want to make sure i'm doing this problem right, any help is appreciated.

find derivative:

log7x^2-1

= log7 + logx^2-1

= lnx^2-1 / ln7

=ln(x+1)(x-1) / ln7

= 1/ln7 + (1/x+1 * 1/x-1)

??

Here is the way to find the derivative of log functions;

Is you function ?

If yes, from the above rule - April 27th 2010, 06:30 PMJGaraffa
ah i knew i forgot brackets somewhere.

the original problem was

log7(x^2-1)
