If tan θ = 3/4 and  θ is acute, then cosec  θ is equal to

If cos⁴ θ - sin4 θ = 2/3, then the value of 1-2 sin² θ is

If tan ∝ = n tan β and sin ∝ Q = m sin β, then cos² ∝ is

If cos θ + sin θ = √2 cos θ, then cos θ - sin θ is

The value of 1/cosec θ - cot θ 

1/sin θ is

The tops of two poles of height 24 m and 36 m are connected by a wire. If the wire makes an angle of 60° with the horizontal, then the length of the wire is
