Derivative of $\sin_dx$ when x is measured in degree

Question

Find the derivative of $\sin_d x,$ if $\sin_d x$ is the sine of $x$ where $x$ is taken to be in degrees.

please help me out solving this math question

@ Lakeside Swagger What are you differentiating it with? If you are differentiating it wrt x in degrees you will get cos x itself as the answer. — Reader Manifold, Jan 18 '18 at 18:42
I feel like a more appropriate notation would be $\sin x°$ where $x$ is a plain number or $\sin x_d$ where $x_d=x°$ — gen-ℤ ready to perish, Jan 18 '18 at 21:56

Hint:

$$\sin_dx=\sin\left(\frac{\pi x}{180}\right)$$
