WebOct 12, 2024 · Solution: Here cosec is positive only in 1st and 2nd Quadrant. 270° does not lies in 1st and 2nd Quadrant. Therefore cosec (360° – θ) = – cosec θ. cosec (270°) = cosec (360° – 90°) cosec (270°) = – cosec (90°) cosec (270°) = – 1 { as per the trigonometry value table cosec90° = 1 } Therefore, the exact value of cosec (270 ...
