Question : Solve for $\theta: \cos ^2 \theta-\sin ^2 \theta=\frac{1}{2}, 0<\theta<90^{\circ}$.
Option 1: 45o
Option 2: 60o
Option 3: 30o
Option 4: 40o
Correct Answer: 30o
Solution : Given, cos2θ − sin2θ = $\frac{1}{2}$ ⇒ cos2θ = $\frac{1}{2}$ + sin2θ since, cos2θ + sin2θ = 1 ⇒ 1 − sin2θ = $\frac{1}{2}$ + sin2θ ⇒ sin

Correct Answer: 600
Solution : Let the time taken by the outlet pipe to empty the tank be $x$ hour. One hour's work of pipe A = $\frac{1}{10}$ One hour's work of pipe B = $\frac{1}{12}$ One hour's work of pipe C = $-\frac{1}{x}$ When all pipes work together, the
Question : $16 \sec ^2 A-16 \tan ^2 A=$_________.
Option 1: 9
Option 2: 0
Option 3: 16
Option 4: 1
Correct Answer: 16
Solution : Given expression, $16 \sec ^2 A-16 \tan ^2 A$ $= 16(\sec^2A-\tan^2A)$ $= 16 × (1)$ $= 16$ Hence, the correct answer is 16.
Question : Two circles of radii 10 cm and 8 cm intersect and the length of the common chord is 12 cm. Then the distance between their centres is:
