Sum of the ages of Anuj, Saroj and Tanuj = 36 × 3 = 108 years So, sum of the ages of Anuj and Saroj = 30 × 2 = 60 years Sum of the ages of Tanuj and Anuj = 36 × 2 = 72 years Therefore, the age of Tanuj = 108 – 60 = 48 years And the age of Saroj = 108 – 72 = 36 years Hence, the average age of Saroj and Tanuj = (36 + 48)/2 = 42 years
If tan θ = 4/3 and θ is an acute angle, find the value of sin θ + cos θ.
If (sinθ+cosθ)/(sinθ-cosθ) = 2, then the value of sin4 θ is
If tanθ = (2/√5), then find the value of cos2 θ
If sin x + cos x = √2 sin x, then the value of sin x - cos x is:
If 4cos2x - 3 = 0, and (0° > x > 90°), then find the value of 'x'.
Take θ = 450
If cos²α + cos²β = 2, then the value of tan⁴α + sin⁸β is
