Trig identities purplemath

WebThe Pythagorean trigonometric identities in trigonometry are derived from the Pythagoras theorem.The following are the 3 Pythagorean trig identities. sin 2 θ + cos 2 θ = 1. This can also be written as 1 - sin 2 θ = cos 2 θ ⇒ 1 - cos 2 θ = sin 2 θ; sec 2 θ - tan 2 θ = 1. This can also be written as sec 2 θ = 1 + tan 2 θ ⇒ sec 2 θ - 1 = tan 2 θ; csc 2 θ - cot 2 θ = 1. WebYou can use this fact to help you keep straight that cosecant goes with sine and secant goes with cosine. The following (particularly the first of the three below) are called "Pythagorean" identities. sin2 (t) + cos2 (t) = 1 tan2 (t) + 1 = sec2 (t) 1 + cot2 (t) = csc2 (t) In mathematics, an "identity" is an equation which is always true.
