Question

Write sin(theta) in terms of cos(theta)​

Answer 1

`\sin(theta) = \sqrt{ {1 - \cos^(2)(theta)} }`

Explanation:

From trignometery identities , we know that :-

`{ \sin^(2)(theta) } + { \cos^(2)(theta) = 1}`

`= { \sin^(2)(theta) } = 1 - { \cos^(2)(theta) }`

Here further solving this , we get

`\sin(theta) = \sqrt{ {1 - \cos^(2)(theta)} }`
