From the figure : Sin A =

The value of tan $\theta$ in terms of sin $\theta$ is

If cosec $\theta$ = 2 and cot $\theta$ = $\sqrt{3p}$ where ‘ $\theta$’ is an acute angle, then p =

If sec $\theta$ = 3K and tan $\theta$ = $\frac{3}{K}$ , then $K^2$ – $\frac{1}{K^2}$ =

tan $\theta$ is not defined when ‘$\theta$’ is

If tan $\theta = \frac{1}{\sqrt3}$, then $7 sin^2 \theta + 3cos^2 \theta =$

If cos 2$\theta$ = sin 4$\theta$, here 2$\theta$, 4$\theta$ are acute angles, then the value of ‘$\theta$’ =
