Question

if y+sin y = cos x , then find the value of y for which dy/dx is Valid​

Answer 1

Answer:

Step-by-step explanation:

34567cos is the answer

Answer 2

Answer:

Step-by-step explanation:

y+sin y = cos x

differentiate with x.o.b.s

dy/dx + dy/dx(siny) = d/dx(cosx)

dy/dx +dy(siny)/dx . dy/dx = -sinx

dy/dx + (cosy) . dy/dx = -sinx

dy/dx (1+cosy) = -sinx

dy/dx = -sinx/1+cosy
