1). √2
2). -√2
3). $\frac{1}{√3}$
4). -1
2. The minimum value of sin2θ + cos2θ + sec2θ + 2cosec2θ + tan2θ
3. What is the value of cosec A sec A cot A - sec A cosec A tan A?
4. θ is a positive acute angle and sinθ cosθ= 0, then the value of secθ + cosecθ is
7. If sinA = 3/5 and 0 < A < π/2 and 27cotA.cos2A = psin2A, then find the value of p.
