Question

Prove the trigonometrical identity. Class 10 ICSE Maths.​

Answer 1

In mathematics, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variable In order to prove trigonometric identities, we generally use other known identities such as Pythagorean identities. Prove that (1−sinx)(1+cscx)=cosxcotx. (1−sinx)(1+cscx)=(1−sinx)(1+1sinx). ( 1 − sin ⁡ x ) ( 1 + csc ⁡ x ) = ( 1 − sin ⁡ x ) ( 1 + 1 sin ⁡ x ) .
