find dy/dx using implicit differentiation
First i change to cos(x)+tan(xy)+1=0
Im using -Fx(x,y) / Fy(x,y)
dy/dx= sin(x)+ysec2(xy) / xsec2(xy)
Right or wrong? Thanks.

If wouldn't ?
Yes. I believe so. Thats what i did on my last step. But i dont know where to go from there to get the final answer.

So it should be
dy/dx= sin(x)-ysec2(xy) / xsec2(xy) correct.
But where to take it from there?

Ah ok. I emailed my professor about this question and it turns out it was a mistake on her part. Yes my answer is correct. Thank you all for the help.
