Trigonometry Quiz 14

Express Tan $\theta$ in terms of Sec $\theta$.

$\frac{Cosec^2 \theta}{Cot \theta} -Cot \theta$

$\sqrt{Cosec^2 \theta - Sin^2 \theta - Cos^2 \theta} =$

If cos $\theta$ = $\frac{2\sqrt{mn}}{m + n}$ ,then sin $\theta$ =

$\frac{Cosec \theta}{Cosec \theta - 1} + \frac{Cosec \theta}{Cosec \theta + 1} =$

Sec $\theta$ (1 – Sin $\theta$) (Sec $\theta$ + Tan $\theta$) =

The ratio of lengths of opposite sides of 30°, 60°, 90° is

If Sin A = Cos B, then ……………………. (A, B are acute)

$\frac{1-sec^2 A}{Cosec^2 A - 1} =$

If Tan $\theta$ + Sec  $\theta$  = 8, then Sec $\theta$ – Tan $\theta$ value is
