Trig Identities Formulas

A formula for computing the trigonometric identities for the third-angle exists but it requires finding the zeroes of the cubic equation where x is the value of the sine function at some angle and d is the known value of the sine function at the triple angle. Secant of angle θ secθ Hypotenuse Base.
