Q. Prove without using

$\frac{\mathrm{sin}\left(90-\mathrm{\theta}\right).\mathrm{sin}\mathrm{\theta}}{\mathrm{tan}\mathrm{\theta}}-1\Rightarrow \u2013{\mathrm{sin}}^{2}\mathrm{\theta}$

Q). If $\mathrm{sin}\theta +\mathrm{cos}\theta =\sqrt{2}\mathrm{cos}\theta $, prove $\mathrm{cos}\theta -\mathrm{sin}\theta =\sqrt{2}\mathrm{sin}\theta $

1. $\left(sec\theta +\mathrm{cos}\theta \right)\left(sec\theta -\mathrm{cos}\theta \right)={\mathrm{tan}}^{2}\theta +{\mathrm{sin}}^{2}\theta .$

2. $\frac{\mathrm{cos}\theta}{1-\mathrm{sin}\theta}=\frac{1+\mathrm{sin}\theta}{\mathrm{cos}{\displaystyle}{\displaystyle \theta}}$

Q. Show that $\mathrm{cos}e{c}^{2}\theta +{\mathrm{sin}}^{2}\theta $ can never be less than 2 .

Q. ${\mathrm{sin}}^{4}A-{\mathrm{cos}}^{2}A={\mathrm{sin}}^{2}A-\mathrm{cos}A$
