The explanations I've found seem to make that jump is that a trig identity or … The functions sin(x) and cos(x) are defined by the picture on the right. The other trigonometric functions are defined by. tan(x) = sin(x)/cos(x); cot(x) = cos(x)/sin(x) 4) Factoring before using identities: 2tanr-2tanz sin2 :=sin(2x).

Trigonometri är det område av matematiken i vilket sambanden mellan en triangels olika storheter beskrivs med trigonometriska funktioner. Trigonometriska funktioner är sammanfattande benämning på de matematiska funktionerna sinus, cosinus, tangens, cotangens, secans och cosecans.

cot (-X) = - cotX , odd function. From basic rules of trigonometry, in a right angle triangle where the opposite is a, the adjacent is b and the hypotenuse is c, sinx is defined by a/c. cosx is defined by b/c and tanx is defined by a/b. sinx / cosx = (a/c) / (b/c) = (a/c) • (c/b).
