Question

Use implicit differentiation to find an equation of the tangent line to the curve at the given point.
sin(x + y) = 2x - 2y at (pi, pi)

Answer 1

@ash2326 are you on

Answer 2

do you know what is meant by implicit differentiation?

Answer 3

take the derivatives of both sides and solve for y'

Answer 4

i got up to cos(x+y)(1+y') = 2(1-y') and i can't figure out how to get the y' on the same side. I may have done something wrong earlier in the problem though so i'm not sure
