Question:medium

Find the value of the trigonometric function cosec (-1410°)

CBSE Class XI

Updated On: Jan 27, 2026

Show Solution

Solution and Explanation

It is known that the values of cosec x repeat after an interval of 2π or 360°.

\(cosec(-1410°)=cosec(-1410°+4×360°)\)

\(=cosec(-1410°+4×1440°)\)

\(cosec\,30°=2\)
