Draw a triangle in the plane with vertices 1 x 1 x 1 0 1 0 and the origin Then arctan x arctan x is the angle between the positive x axis and the ray beginning at the origin and Apply the identity tan a b tan a tan b 1 tan a tan b to arctan 4x arccos x This gives us arctan 4x arctan x 1 4x 2 Next we can simplify further by using the identity
It uses functions such as sine cosine and tangent to describe the ratios of the sides of a right triangle based on its angles The three basic trigonometric functions are Sine sin Cosine Let B r sin theta and A r cos theta which can be any two numbers Then if A ne0 the equation turns to arccos cos theta arctan tan theta
