E𝑥3.2, 7 Find the value of the trigonometric function cosec (–1410°) cosec (–1410°) = – cosec (1410°) = – cosec (1410 × 𝜋/180) = – cosec (47𝜋/6) = – cosec (75/6 𝜋) = – cosec (8π – 1/6 π ) = – cosec (– 1/6 π ) = – cosec (– 1/6 × 180° ) = – cosec (–30°) = – (– cosec 30°) = cosec 30° = 1/sin⁡〖30°〗 = 1/(( 1/2 ) ) = 2/1 = 2
