The logic is followed here- 36 – 21 = 15 x 2 + 5 = 35 43 – 19 = 24 x 2 + 5 = 53 Similarly, 51 – 34 = 17 x 2 + 5 = 39
Simplify: sin (A + B) sin (A - B)
(cos5°+sin5°)/(cos5°-sin5°) is equal to:
If sin(3x - 2o) = cos(2x + 22o), then find the value of: {3tan(4x - 11o) + cosec(5x - 10o)} X cot(2x + 2
If cos² x + sin x = 5/4, then find the value of 'sin x'.
If (sinθ+cosθ)/(sinθ-cosθ) = 2, then the value of sin4 θ is
If {(tanx)/(secx)} × cosx = (1/2), then determine the value of ‘sin2x’.
If 9 sinx + 40 cosx = 41 then find tanx.
If tan α = 1/2, tan β = 1/3, then find α + β.
