This is a geometric way to prove the particular tangent half-angle formula that says tan 1 / 2 (a + b) = (sin a + sin b) / (cos a + cos b). The formulae sin 1 / 2 (a + b) and cos 1 / 2 (a + b) are the ratios of the actual distances to the length of the diagonal. See more In trigonometry, tangent half-angle formulas relate the tangent of half of an angle to trigonometric functions of the entire angle. The tangent of half an angle is the stereographic projection of the circle onto a line. Among … See more Comparing the hyperbolic identities to the circular ones, one notices that they involve the same functions of t, just permuted. If we identify the parameter t in both cases we arrive at a relationship between the circular functions and the hyperbolic ones. That is, if See more • Mathematics portal • List of trigonometric identities • Half-side formula See more Algebraic proofs Using double-angle formulae and the Pythagorean identity See more In various applications of trigonometry, it is useful to rewrite the trigonometric functions (such as sine and cosine) in terms of rational functions of a new variable $${\displaystyle t}$$. These identities are known collectively as the tangent half-angle formulae … See more If tan φ/2 is a rational number then each of sin φ, cos φ, tan φ, sec φ, csc φ, and cot φ will be a rational number (or be infinite).
