Re: Implicit Differentiation

You differentiated correctly, now use the given point (2,-12) to find y'(2). Then use the point-slope formula to find the equation of the tangent line.

Re: Implicit Differentiation

Instead of making a new thread on these, I want to just pop in a quick question to see if I implicitly differentiated this correctly; problem is , and I implicitly differentiated y with respect to x to get this ... Does that look about right? I have a gut feeling it isn't, but I've combed through it a few times and I'm not sure how else to differentiate it. Thanks!

Re: Implicit Differentiation

I get a different result...can you post your work?

Re: Implicit Differentiation

Thanks for your help, I think I got it. The slope came out to -11/2 and the equation for the tangent line came out to be y=-11/2(x)-1. Thanks again!!

Re: Implicit Differentiation

Yes, I get the same result. :)
