Question

If y = x cos y + y cos x then find dy/dx
​

Answer 1

Step-by-step explanation:

dy/dx= cosy+ x(-siny)dy/dx + dy/dxcosx + y(-sinx)

dy/dx=cosy-ysinx +(cosx-xsiny)dy/dx

(1-cosx+siny)dy/dx= cosy- ysinx

dy/dx = (cosy- ysinx)/(1-cosx+siny)

hope this will help u

Answer 2

Answer:

cosy-sinx/(1-xsiny-cosx)

Step-by-step explanation:

just apply inline differentiation method
