WitrynaAlso, secant is reciprocal of cos,i.e., sec θ = (1/cosθ) For the secant of an angle, there is a formula related to the Pythagoras theorem, i.e. Sec 2 θ = 1 + tan 2 θ . Note: This equation is very useful. It is similar to the squared relationship between sin θ and cos θ. (i.e. Sec 2 θ - tan 2 θ = 1) Witryna3 kwi 2024 · Sec x, is the reciprocal of cos x. sec x = 1 / cos x; Cot x is the reciprocal of tan x. cot x = 1 / tan x; Out of the six fundamental trigonometric functions, you will mostly be concerned with sin, cos, and tan.
