Q. Express as a function of a DIFFERENT angle, 0∘≤θ<360∘.sin(309∘)sin(□∘)
Understand the problem: Understand the problem.We need to express sin(309∘) in terms of a different angle that is within the range of 0∘ to 360∘. This typically involves using known trigonometric identities or properties to rewrite the sine of an angle in terms of another angle.
Use trigonometric identities: Use the fact that sin(θ)=sin(180°−θ) or sin(360°−θ) to find an equivalent expression.Since 309° is more than 180°, we can use the identity sin(θ)=sin(360°−θ) to find a different angle that gives the same sine value.
Calculate equivalent angle: Calculate the equivalent angle using the identity.sin(309°)=sin(360°−309°)sin(309°)=sin(51°)
Verify new angle: Verify that the new angle is within the specified range.51° is indeed within the range of 0° to 360°, so our expression is valid.
