die();
why

why
i slept through it during senior year and i skipped class that week this semester.
Ok, differentiate the term as it was in terms of x, and add dy/dx. *This is assuming you are only using x and y terms.

what if i had to find dy/dx and i had like
3xy=y
i think that was problem but it might not have been i forget

Um, subtract y before differentiating.
3xy-y=0
d/dx(3xy-y)=0
3x(dy/dx)+y(3)-(dy/dx)=0
(3x-1)(dy/dx)=-3y
dy/dx=(-3y/3x-1)

doesn't really matter
i know but my p's and q's get in a jumble

how did you do that
we do a product rule for the first term
Looking at that problem, I don't believe that is a valid equation. You can't graph it. You can't have y=3y.

Yes you could. Constant function; y=0.
Wow, you guys move slow for a college class

ah yes you could
But really, that's a strange problem.
I'm in geometry.

ok find the tangent line with a circle of radius 4 whose center is at (0,0) at the point (0,4)
