Calculus

What is the slope of the tangent to the curve y^3x + y^2x^2 = 6 at (2,1)

I'm confused what to do am I supposed to isolate y??


I see you have graph paper.
You must be plotting something

Re: Calculus

That is what I get.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Re: Calculus

do i need (xy^2)(x+y)=6 or something?

Re: Calculus

You should use implicit differentiation.
