Q. Express as a function of a DIFFERENT angle, 0∘≤θ<360∘.sin(332∘)sin(□∘)
Find Equivalent Angle: We need to find an equivalent angle for 332∘ that falls within the first or second quadrant (0∘ to 180∘) to express sin(332∘) as a function of a different angle. We can use the fact that sine is a periodic function with a period of 360∘, and that sin(θ)=sin(360∘−θ) for angles in the fourth quadrant.
Calculate Reference Angle: Calculate the reference angle for 332∘. The reference angle is the acute angle formed by the terminal side of the angle and the x-axis. For an angle in the fourth quadrant, the reference angle is 360∘−θ.
Substitute into Formula: Substitute 332∘ into the reference angle formula: reference angle = 360∘−332∘=28∘.
Express as sin(28°): Now we can express sin(332°) as sin(360°−28°), which is equivalent to sin(28°) because sine is a co-function of its complement.
Final Result: Since 28° is in the first quadrant, where sine is positive, we can say that sin(332°)=sin(28°).
