Question
Determined the simplified value of the given
expression:(1 - sin2Ā q) X (sec q + tan q) X (sec q - tan q) X cosec2Ā qSolution
(1 - sin2Ā q) X (sec q + tan q) X (sec q - tan q) X cosec2Ā q= cos2Ā q X (sec2Ā q - tan2Ā q) X cosec2Ā q ...... (Using sin2Ā a + cos2Ā a = 1)= cos2Ā q X (1/sin2Ā q) ....... (Using sec2Ā a - tan2Ā a = 1)= cotĀ²Ā q
