Q. Find all solutions with −90∘≤θ≤90∘. Give the exact answer(s) in simplest form. If there are multiple answers, separate them with commas.csc(θ)=−1____∘
Identify Angle:csc(θ)=−1Identify the angle where the value of cosecant is −1.The cosecant function is the reciprocal of the sine function, so csc(θ)=sin(θ)1. Therefore, we are looking for angles where sin(θ)=−1.
Find Minimum Point: Find the angle within the given range where sin(θ)=−1. The sine function reaches a value of −1 at its minimum point in its cycle. Within the range –90°≤θ≤90°, this occurs at θ=−90°.
Verify Solution: Verify that the solution is within the given range.The angle θ=−90∘ is within the range −90∘≤θ≤90∘.
