If `y=xsin(a+y)` , prove that `(dy)/(dx)=(s in^2(a+y))/(sin(a+y)-y\ cos\ (a+y))` .

Text Solution

Verified by Experts

Here $$ y=x \sin (a+y) $$ Differentiating it with respect to `x` using the chain rule and product rule, $$ \frac{d y}{d x}=x \frac{d}{d x} \sin (a+y)+\sin (a+y) \frac{d x}{d x} $$ ...
