Question

find dy/dy of y + sinxy = x

Answer 1

question is wrong

Answer 2

sorry it is Find dy/dx by implicit differentiation.

Answer 3

ya thats true

Answer 4

dy/dx is still wrong?

Answer 5

on differention dy wrt to dy

Answer 6

Differentiate both sides,
dy/dx+cos(xy) dy/dx=1
=>dy/dx(1+cos xy)=1
=> dy/dx=1/(1+cos(xy))

Answer 7

Remember to differentiate the (xy) term in sin(xy) to get correct answer!

Answer 8

Question is find dy/dx of y+sinxy=x

Answer 9

ok 1+cos(xy) x=0
cosxy=-1/x

Answer 10

ok thanks all
