$\cos \theta = \frac{b}{\sqrt{a^2 + b^2}}$; જ્યાં,$0 < \theta < 90^\circ$; તો $\sin \theta = \dots$

સાબિત કરો કે $\frac{\cos ^{2}\left(45^{\circ}+\theta\right)+\cos ^{2}\left(45^{\circ}-\theta\right)}{\tan \left(60^{\circ}+\theta\right) \tan \left(30^{\circ}-\theta\right)}=1$

સાબિત કરો કે,$\tan \theta + \tan (90^{\circ} - \theta) = \sec \theta \sec (90^{\circ} - \theta)$

$\Delta ABC$ માં, $AC = 5$, $BC = 13$, $m \angle A = 90^\circ$ હોય, તો $\tan B = \ldots$

જો $\sec \theta = 1$ હોય,તો $\theta = \ldots \ldots \ldots$ ($^{\circ}$ માં)
