I am converting some radians to degrees. I would assume that sin(1°) = sin(pi/180) yes? Since 1°=pi/180. So by algebraic defaults, this should hold true..

But I am getting strange values in these three calculations:
sin-356° - Wolfram|Alpha

sin4° - Wolfram|Alpha

sin364° - Wolfram|Alpha

They all state that the respected degrees equal pi/45 rad..

To my knowledge, $\frac{\pi}{45}=4\deg$ which holds true for the 2nd calculation in my row there.

However, if I convert 364 degrees to radians I do it like this: $1deg=\frac{\pi}{180}$ so $364deg=\frac{364\cdot \pi}{180}$ which I do not understand how becomes $\frac{\pi}{45}$

It's probably just some fundamental issue that I am overlooking as usual, but I would appreciate some direction here. Thanks.
