The following are double angle formula, values of trigonometric functions, half angle formula. Trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables where both sides of the equality are defined. The distance from origin 0 to point p is positive and denoted by r = √x2 + y2.

Trigonometric formulas for sum and difference, double angle, half angle, product and periodicity identities.

Compute the trigonometric value of a double angle without a calculator. And this calculator solution avoids all three goals. Verifying trigonometric identities with double angle formulas. With these formulas, it is better to remember where they come from, rather than trying to remember the actual formulas.
