Angle An angle is the figure formed by two lines diverging from a common point. Arcsin arcsin is the inverse function of the sine function. This means that if x is a value between 0º and 90º, then arcsin(sin x) = x and sin(arcsin x) = x Arccos arccos is the inverse function of the cosine function. This means that if x is a value between 0º and 90º, then arccos(cos x) = x and cos(arccos x) = x Arctan arctan is the inverse function of the tangent function. This means that if x is a value between 0º and 90º, then arctan(tan x) = x and tan(arctan x) = x Base © 1998 - 2010 Softmath 99
