Find the derivative
Hi guys, Could someone tell me if this is correct?
Find the derrivative of the function:
$\displaystyle (x^21)/(2x3)$
(This is a fraction but i can't figure out the forum codes)
The answer I get after working this out is:
$\displaystyle 2/(2x3) $

It is simple just use the quotient rule Attachment 26749

Re: Find the derivative
Look at it likethis:
Product:
$\displaystyle \frac{dy}{dx}\left[(x^21)(2x3)^{1}\right]$
$\displaystyle =\overbrace{(x^21)(1)(2x3)^{2}(2)}^{\text{first times derivative of second}}\underbrace{+}_{\text{plus}}\overbrace{(2x3)^{1}(2x)}^{\text{second times drivative of first}}$
