Question

use implicit differentiation to find dy/dx of cos(x−y)+siny=√2

Answer 1

dy/dx = 0

Answer 2

are you sure? how did you get that?

Answer 3

dy/dx=-f'y/f'x
f'y already equals 0 so dy/dx=0

Answer 4

differentiating with respect to x.
-sin(x-y)(-dy/dx)+cosy dy/dx = 0
dy/dx (cosy + sin(x-y))=0
dy/dx = 0

Answer 5

so what's the equation for the tangent line at \[(\pi/2, \pi/4)\]

Answer 6

i guess that's what i got too I just didn't think it was right because now i don't get how to do the equation for the tangent line @u1umer

Answer 7

thanks

Answer 8

hey could you help me find the equation of the tangent line?

Answer 9

y= pie/4 equ of tangent line
