How to get sine and cosine?

So, I’m making a thing that rotates the camera around an object, and I need to get the sine and cosine of an angle (degrees).
How do I do that in C#?

Watch out:

Note that Mathf.Sin and Mathf.Cos does not take angles degrees but in radians. This is common in math since that’s how sine and cosine works internally / numerically.

Unity provides two conversion factors you can use to convert degrees to radians or vice versa

// convert degree to radian
float rad = degree * Mathf.Deg2Rad;

// convert radian to degree
float deg = radian * Mathf.Rad2Deg;

Radians are define as the arc-length on the unit circle. So a full circle would be 2*PI.

360° -> 2*PI
180° -> PI
90° => PI/2
...

Nevermind, I found out, it’s

Mathf.Sin()
// And
Mathf.Cos()

But how do I SET an object’s rotation?
