trig rules In trigonometry trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined Geometrically these are identities involving certain
Basic trig identities are formulas for angle sums differences products and quotients and they let you find exact values for trig expressions The three main functions in trigonometry are Sine Cosine and Tangent They are just the length of one side divided by another For a right triangle with an angle Sine Function sin Opposite Hypotenuse Cosine Function cos Adjacent Hypotenuse Tangent Function tan Opposite Adjacent
