Exam specification: Edexcel > Maths A-level > C2 > Trigonometry
Solution in a given interval.
Students should be able to solve equations such as sin (x + π/2) = 3/4 for 0 < x < 2?, cos (x + 30°) = 1/2 for ?180° < x < 180°, tan 2x = 1 for 90° < x < 270°, 6 cos2 x + sin x ? 5 = 0, 0° ? x < 360, sin2(x + π/6) = 1/2 for -π ≤ x < π.
