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.tan(θ)=1____∘
Identify Tangent Relationship: Since tan(θ)=cos(θ)sin(θ), we're looking for angles where the sine and cosine are equal because tan(θ)=1 means sin(θ)=cos(θ).
Find Angle in First Quadrant: In the first quadrant, tan(θ)=1 at θ=45∘ because sin(45∘)=cos(45∘)=2/2.
Consider First Quadrant Only: In the third quadrant, tan(θ)=1 would also occur, but since we're looking for -90^\circ < \theta < 90^\circ, we only consider the first quadrant.
Final Solution: Therefore, the only solution within the given interval is θ=45∘.
