What is the value of $\frac{cos^{2}A}{(1 + sinA)}$?
1). 1 + sinA
2). 1 - sinA
3). 1 - secA
4). 1 + secA
1. The value of $(sin^{2}25^{0} + sin^{2}65^{0})$ is :
3. If $0^{0} < \theta < 90^{0}$ and $2 sec\theta$ = $3 cosec^{2}\theta$ , then $\theta$ is
5. $\triangle XYZ$ is right angled at Y. If $m\angle Z$ =$ 60^{0}$, then Cosec X =
6. If cosec2θ – (1 + √3) cotθ + √3 – 1 = 0, then the value of cot θ is:
8. If θ is acute angle and sin(θ+18°)= 1/2, then the value of θ in circular measure is
10. If $Sin\theta $ = $\frac{20}{29}$ , then what is the value of $Sec Sin\theta $ ?
