  Radians are the objectivly better way to do angles tho. Just remeber π=180deg and ur right. Btw here is a another brain fuck the units radians/second is just Hz

    Thank you for reminding me!

    Btw, Radians/sec = Hz? What is this, physics?

      The easiest way to think about it is that 1 full rotation (pi radians) in 1 second makes 1 Hz.

      The number of rotations made in a second corresponds to Hz in the same way that the number of sine wave periods that fit in a second also represents Hz. This gif does a really good job of showing how rotation relates to sine/cosine waves, which just so happens to help visualize the rad/s -> Hz <- periods/s relationship:

      Engineering unit maths. Cos angles are unitless so radians/second =1/second=Hz

    Yes, and tau is objectively better than pi. Just remember tau = 360°. Which is a full circle, which easier to work with than half a circle.
