Source Code

;; Defined in /usr/src/emacs/lisp/calc/calc-math.el.gz
;; This could use a smarter method:  Reduce x as in math-sin-raw, then
;;   compute either sin(x) or cos(x), whichever is smaller, and compute
;;   the other using the identity sin(x)^2 + cos(x)^2 = 1.
(defun math-sin-cos-raw (x)   ; [F.F F]  (result is (sin x . cos x))
