Given: secx + tanx = 3 Concept Used: If secx + tanx = y. then secx - tanx = 1/y cosec2x - cot2x = 1 tanx = 1/cotx. Sep 1, 2011 ... i.e. tanx = 1. This means (in this interval) that x = π/4. So π/4 is the only critical number. This means we have to check the points 0, π/4 ... sinx tan x = sin x for 0≤ x < 2π . a) π -- 4, b) π 5π --, --- 4 4, c) π 0 ... ⇒ sin x tanx - sin x = 0 ⇒ sin x(tanx - 1. It follows that. sin x = 0 ⇒ x ...
