I think that's x radians so multiply it by 180/pi to convert it to degrees

So that's y = sin(180x/pi)

thus y' = 180/pi x cos(180x/pi) and you can convert it back to radians

It is not exactly clear what are trying to ask.

What ratio do you want the amplitude to be with respect to half the period. 1:180 or 1: i

Presuming want the former than:

y' = pi/180 * cos(x)

This more complicated than if ratio is 1: i. As if you let pi radians = 180 degrees, you will end up with y' = cos(x).

The proof of the theorem sin(x) d/dx = cos(x) is beyond the scope of advanced maths so just accept the theorem.
