Step 3: Now, sin θ =Perpendicular/ Hypotenuse= (AC) /(AB)ġ= sin 2θ + cos 2θ Trigonometric Identity 2 (AB) 2= (AC) 2+ (BC) 2 let be equation (1)ĭividing equation 1 by square of AB on both the sides, Step 1: Consider a right angle triangle ABC, let angle C be of 90. (Hypotenuse) 2= (Base) 2 + (Perpendicular) 2 According to Pythagorean theorem for any right angle triangle: Assume AC be base and BC be perpendicular.

If angle C is at 90 degrees then AB will be the hypotenuse. Trigonometric Identity 1īefore derivation let’s understand what is Pythagoras Theorem? For any right-angled triangle, let ABC be our right angle triangle. The following are the relations or identities derived from Pythagoras theorem, that’s why they are called Pythagorean relations.

sin θ = 1/ cosec θ or sin θ x cosec θ = 1Īgain, as the name suggests, quotient relations involve three trigonometric ratios where one is the quotient obtained after division operation between the other two.

Trigonometric Relations Reciprocal RelationshipĪs the name suggests, these relations involve two trigonometric ratios which are connected by inverse relations between them.

The equations can be seen as facts written in a mathematical form, that is true for “ right angle triangle”. The same applies to trigonometric identities also. For example (x+1) 2=x 2+2x+1 is an identity in x. In algebraic form, an identity in x is satisfied by some particular value of x.
