Calculate the value of A, if : (sec 2A - 1) (cosec 3A - 1) = 0

Question

KnowledgeBoat · Accepted Answer

(sec 2A - 1) (cosec 3A - 1) = 0 ⇒ sec 2A - 1 = 0 and cosec 3A - 1 = 0 ⇒ sec 2A = 1 and cosec 3A = 1 ⇒ sec 2A = sec 0° and cosec 3A = cosec 90° So, 2A = 0° and 3A = 90° ⇒ A = 0° and A = Hence, A = 0° and 30°.
