Question

How do you differentiate sinx−siny=x−y−5?

Answer 1

Answer:dy/dx = (1-cosx) /(1-cosy)

Step-by-step explanation:

sinx - siny= x - y -5

Simply we diff w.r.t 'x'(if you want you also diff w.r.t 'y')

cosx-(cosy (dy/dx))=1-(dy/dx)-0

Now arrange it

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

dy/dx(1-cosy)=1-cosx

Now we are at end

dy/dx = (1-cosx) /(1-cosy)
