Other useful identities involving the tangent are the half-angle formula, tan (A/2) = 1 − cos A/sin A;the double-angle formula,tan 2A = 2 tan A/1 − tan2 A;the addition formula, tan (A + B) = tan A + tan B/1 − tan A tan B; and the subtraction formula, tan (A...
A beautiful formula that generalizes the tangent angle addition formula, (27), and (28) is given by (29) (Szmulowicz 2005). There are a number of simple but interesting tangent identities based on those given above, including (30) (Borchardt and Perrott 1930). The Maclaurin serie...
The three theorems for the intercepted arcs to the angle of two tangents, two secants or 1 tangent and 1 secant are summarized by the pictures below. If you look at each theorem, you really only need to remember ONE formula. The angle formed by the intersection of 2 tangents, 2 secant...
Formulas for the trigonometric functions of multiple arguments can be derived from the addition formulas—for example, The above identities are often called double-angle formulas. Formulas that express the powers of the sine and cosine of an argument in terms of the sine and cosine of multiples ...
