2 days ago · The tangent function is defined for real numbers x with cosx!=0 by tanx=(sinx)/(cosx), (1) where sinx is the sine function and cosx is the cosine function. The notation tgx is sometimes also used (Gradshteyn and Ryzhik 2000, p. xxix). For an acute angle theta in a right triangle, its tangent is the ratio of the side lengths opposite to the angle and adjacent to the angle, i.e., tantheta ...
