Find the value of sin(θ) if 2sinθ = tanθ, for 0 < θ < 90°.
If cot A = 12/5, then the value of (sin A + cos A) × sec A is ________.
If sin A = (4/5), then find the value of {cosec A × cos A + sec A × tan A}.
If A + B = 450 , then the value of 2(1 + tanA) (1 + tanB) is:
which of the following is equal to [(tan θ +secθ -1)/ (tanθ-secθ +1)]
