If θ is an acute angle and tan θ + cot θ = 2 , then the value of tan²⁵θ+cot²⁵θ is

Given that: SinA = a/b, then cosA = ?

The maximum value of 1/secθ is

If sinθ=5/13 then cosθ =

A boat is sailing towards a lighthouse of height 20$\sqrt{3}$ m at a certain speed. The angle of elevation of the top of the lighthouse changes from 30° to 60° in 10 seconds. What is the time taken (in seconds) by the boat to reach the lighthouse from its initial position?

The value of the expression [cosec (75° + θ) – sec (15° - θ) – tan (55° + θ) + cot (35° - θ)] is.

If cos θ = $\frac{4}{5}$; then the value of $\frac{\cos ec\theta }{1+cot\theta }$ is:

If A, B and C are interior angles of a triangle ABC, then what is the value of tan (B+C/2)?

The minimum value of 2sin²θ + 3cos²θ is:

If tanθ = $\frac{1}{\sqrt{11}}$ and 0 < θ < $\frac{\pi }{2}$ ; then the value of $\frac{\cos e{c}^2\theta -se{c}^2\theta }{\cos e{c}^2\theta +se{c}^2\theta }$ is:

If cos(A/2) = x; then the value of x is: 

If secθ + tanθ = 2; then the value of secθ is:
