Having coded a 3D engine: sin and cos are cool. Tan can fuck right off. Atan doubly so.
And radians are the devil's work.
fuck you radians are cool and atan is actually incredibly useful , so much they made atan2
tan is also ok ig
atan2, on the other hand, is just awesome.
Anything that is "degrees" is the devils work. Radians are so neat and IIRC it makes a lot of trigonometry math easier. Yes, they're a bit weird to get into once one has been indoctrinated to degrees, but (pi/2) radians is just so nice.
Yeah I fuckin' love dealing with transcendental constants and fractions just to describe a right angle. A quarter-circle being one-half just makes so much sense! It's awesome seeing all these mantissa-only numbers, because you can totally tell apart sane results and srand() without doing floating-point math in your head!
