Find dy/dx using implicit differentiation of xy + sin^2y=10350.
Is it y/(x+2siny)

Hmm. I get sin2y
y + xy' = 2siny*cosy y' = 0
y' = y/(x + 2siny cosy)
= y/(x + sin2y)
don't forget that chain rule. . .

Hi, I'm having trouble using implicit differentiation to determine dy/dx in the form dy/dx = f(x,y) for sin(2x+3y)=3x^3y^2+4 Do I make it sin(2x+3y)3x^3y^2=4 then differentiate to get 2cos(2x+3y)9x^2*2y=0 ?
