Find the dervative of 7x-6/y

With respect to what?

Are those both functions of some variable? Is y a function of x?

I'll assume for now that they are both functions of t.

Then $\displaystyle \frac{d}{dt} \left( 7x - \frac{6}{y} \right) = 7 \cdot \frac{dx}{dt} + \frac{6}{y^2} \cdot \frac{dy}{dt}$.

I hope that's what you're after. - Nov 12th 2006, 10:06 PMNimmy
Yes it is y is a function of x

the equation is wrong it is: (7x-6)/(y) - Nov 13th 2006, 03:21 AMtopsquark
