Trigonometric Identity

trigonometry identities showing that the identity is always true, no matter what value of x or θ is used. Because it has to hold true for all values of x, we cannot simply substitute in a few values of x to “show” that they are equal.  We have to use logical steps to show that one […]

Trigonometric identity

Trig identity is equations that are true for Right Angled Triangles. D1‎: ‎sin 2A+ cos 2A=1 D2‎: ‎1+ tan 2A= sec 2A D3‎: ‎1+ cot 2A= csc 2A Hence trigonometric identities are prove by  above D1,D2 and D3. Similarly also using reciprocal identity. Trigonometric Identity
