Lightweight trigonometry doc (#1356)

Browse source 
* Doc units of trig functions

* "Very simple" yet I made a mistake

* sins returns in [-0x7FFF,0x7FFF] as the [-1,1] range

* Also `sys_math_atan.c`

* Remove `@param`s without descriptions

* Add note on Math_Atan2S/F arguments being unlike atan2

* "from (1,0) to (x,y)" -> "from vector ..."

* arg names -> `angle`

* Improve `@return` comment on atans
