how does the derivative of

-1/ (x - 1)^2

=

2/ (x - 1)^3

seems simple..but i get x in the numerator :(

It should be easy now

Right? :D - Apr 15th 2010, 06:32 AMcalculus0
thank you but do you know how do do it with quotient rule? my teacher emphasizes this.

im so horrible at this..

after 1/2 the equation disappears multiplying by zero i get:

2

-----------

(x - 1)

which is not equal to the solution

2

------------

(x - 1)^3 - Apr 15th 2010, 07:58 AMe^(i*pi)

think i got it...e^(i*pi)

thanks so much
