Trigonometric Identities (List of Trigonometric Identities Proofs

WebPythagorean identities are important identities in trigonometry that are derived from the Pythagoras theorem. These identities are used in solving many trigonometric problems where one trigonometric ratio is given and the other ratios are to be found. The fundamental Pythagorean identity gives the relation between sin and cos and it is the most commonly … WebFor the next trigonometric identities we start with Pythagoras' Theorem: Dividing through by c2 gives a2 c2 + b2 c2 = c2 c2 This can be simplified to: ( a c )2 + ( b c )2 = 1 Now, a/c is Opposite / Hypotenuse, which is sin (θ) And b/c is Adjacent / Hypotenuse, which is cos (θ) So (a/c) 2 + (b/c) 2 = 1 can also be written: sin 2 θ + cos 2 θ = 1
