If 0 ≤ θ ≤ 90°, and sec¹⁰⁷ θ + cos¹⁰⁷ θ = 2, then. (secθ + cosθ) is equal to:

If (x - 1/x)² = 3, then the value of x⁶ + 1/x⁶ equals

If 2cos² Ɵ – 5cos Ɵ + 2 = 0,0⁰ < Ɵ < 90⁰ , then the value of (cosec Ɵ + cot Ɵ) is :

If 2y cos θ  = x sin θ  and 2x sec θ -  y cosec θ  = 3, then the value of x²+ 4y² is

If 3x + 5y + 7z = 49 and 9x + 8y + 21z = 126, then what is the value of y?

The value of = 3/4 ÷ 3/4  of 4/3 + 5/2 ÷ 2/5 of 5/4 – (2/3 + 2/3 of 5/6) is :

The simple interest accrued on a sum at the rate of 10% p.a. for two years is Rs. 5,000.

The expression of (cot θ + cosec θ −1) / (cot θ − cosec θ+1) is equal to

Quantity I – ³
