Proving identities

Proof of the reciprocal identities proof of the tangent and cotangent identities proof of the pythagorean identities. Here we will prove the problems on trigonometric identities in an identity there are two sides of the equation, one side is known as ‘left hand side’ and the other side is known as ‘right hand side’. Trig identities identities involving trig functions are listed below pythagorean identities sin 2 θ + cos 2 θ = 1 tan 2 θ + 1 = sec 2. Trigonometric identities reciprocal identities sinu= 1 cscu cosu= 1 secu tanu= 1 cotu cotu= 1 tanu cscu= 1 sinu secu= 1 cosu pythagorean identities sin 2u co.
