To verify: The given equation is an identity.

Expert Solution & Answer
Check Mark

Explanation of Solution

Given information: Given equation is cos(90°+θ)=sinθ .

Verification:

  cos(90°+θ)=sinθ

Using sum and difference identity,

  cos90°cosθsin90°sinθ=sinθ0(cosθ)1(sinθ)=sinθsinθ=sinθ

Thus, the given equation is an identity.

Hence proved.
