Using trigonometric identities Trigonometric identities like sin cos 1 can be used to rewrite expressions in a different more convenient way For example 1 sin cos can be rewritten as cos cos and then as cos Created by Sal Khan All the trigonometric identities are based on the six trigonometric ratios They are sine cosine tangent cosecant secant and cotangent All these trigonometric ratios are defined using the sides of the right triangle such as an adjacent side opposite side and hypotenuse side
In mathematics an identity is an equation which is always true regardless of the specific value of a given variable An identity can be trivially true such as the equation x x or an identity can be usefully true such as the Pythagorean Theorem s a2 b2 c2 Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles In particular the trigonometric functions relate the angles of a right triangle with ratios of its side lengths
