Question : If $\alpha +\beta =90^{\circ}$, then the expression $\frac{\tan \alpha}{\tan \beta}+\sin^{2}\alpha+\sin^{2}\beta$ is equal to:
Option 1: $\sec^{2}\beta$
Option 2: $\tan^{2}\alpha$
Option 3: $\tan^{2}\beta$
Option 4: $\sec^{2}\alpha$
Correct Answer: $\sec^{2}\alpha$
Solution : Given: $\alpha +\beta =90^{\circ}$ Since $\alpha +\beta =90^{\circ}$ $\alpha = 90^{\circ} - \beta$ $\tan\alpha = \tan (90^{\circ} - \beta) = \cot \beta$ $\sin\alpha = \sin (90^{\circ} - \beta) = \cos\beta$. From the given expression, $\frac{\tan \alpha}{\tan \beta}+\sin^{2}\alpha+\sin^{2}\beta$ $ =\frac{\cot \beta}{\tan \beta} + \cos^{2}\beta + \sin^{2}\beta$
