WebLet us see the stepwise derivation of the formula for the tangent trigonometric function of the sum of two angles. In the geometrical proof of tan(a+b) formula, let us initially assume that 'a', 'b', and (a + b) are positive acute angles, i.e. (a + b) < 90. But this formula, in general, is true for any positive or negative value of a and b.
