WitrynaSince the hypotenuse is always longer than the two legs, this ratio is always less than 1. Moreover, since the angles adjacent to a leg and opposite a leg are related by α = π / 2 − β, the sine and cosine necessarily have similar forms. By contrast, the tangent is the ratio of the legs to each other, and this can take on any value and goes ... WitrynaSo, it is quite impressive that you notice this. Also, unlike the other "definitions" of the trig functions that are usually given at this level of study, tan x = sin x /cos x is always true for all angles, not just right triangles. You will note that tangent is undefined at values of x where cos x = 0. 2) The standard symbol for tangent is "tan".
