Question

2. If sino =11/61
find the values of cosec0 using trigonometric identity.​

Answer 1

sin⁡θ=1161

, find the values of cosθ using trigonometric identity.

SOLUTION

We have,

sin2⁡θ+cos2⁡θ=1

⇒cos2⁡θ=1−sin2⁡θ

⇒cos2⁡θ=1−(1161)2

⇒cos2⁡θ=1−1213721=3721−1213721=36003721

⇒cos⁡θ=(6061)2=6061

Thus, the value of cosθ is

6061
