When 0°< θ < 90°, and 2cos θ = 1 the value of θ is
If tanθ > 0, sinθ > 0, then the terminal arm of the angle lies in the quadrant
The value of cos θ cos(90°  θ) – sin θ sin (90°  θ) is:
tan^{2}A – tan^{2}B can also be written as.
The value of θ for which 2 cos^{2}θ + sinθ  2 = 0; 0° < θ < 90° is:
If 2 cos(A + B) = 1, and 2 sin(A –B) = 1 then the values of A and B are
If a cosθ + b sinθ = 4 and a sinθ – b cosθ = 3, then a^{2} + b^{2} is
If θ is an acute angle and tan θ + cot θ = 2, then the value of tan^{7}θ + cot^{7}θ is is
