Q. Express as a function of a DIFFERENT angle, 0∘≤θ<360∘.sin(344∘)sin(□∘)
Understand Period of Sine Function: Recognize that the sine function has a period of 360°, which means that sin(θ)=sin(θ+360°k), where k is an integer. However, since we want to express sin(344°) as a function of a different angle within the range of 0° to 360°, we need to find an angle that is coterminal with 344° and falls within the specified range.
Find Coterminal Angle: To find a coterminal angle that is within the range of 0∘ to 360∘, we can subtract 360∘ from 344∘ if the angle is greater than 360∘, or add 360∘ if the angle is less than 0∘. Since 344∘ is less than 360∘, we can find a coterminal angle by subtracting 344∘ from 360∘.
Calculate Coterminal Angle: Calculate the coterminal angle by subtracting 344∘ from 360∘. 360∘−344∘=16∘So, sin(344∘) is equivalent to sin(360∘−16∘), which is sin(16∘) because sine is an odd function, and sin(−θ)=−sin(θ).
Express as Different Angle: Since sin(344°)=sin(16°), we have expressed sin(344°) as a function of a different angle within the range of 0° to 360°.
