Only Pesos are Rubles + No Ruble is a Euro (E) → → No conclusion. Hence neither conclusion I nor III follows but it will make a complementary pair. Hence either conclusion I or III follows. Some Dollars are Rupees (I) + All Rupees are Euros (A) → Some Dollars are Euros (I). Hence conclusion II follows.
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
