Question : The value of $\frac{\cot30^{\circ}-\cot75^{\circ}}{\tan15^{\circ}-\tan60^{\circ}}$ is equal to:
Option 1: –1
Option 2: 0
Option 3: 1
Option 4: 2
Correct Answer: –1
Solution : We know that $\tan(90-\theta)=\cot \theta$ $\frac{\cot30^{\circ}-\cot75^{\circ}}{\tan15^{\circ}-\tan60^{\circ}}$ = $\frac{\tan(90^{\circ}-30^{\circ})-\tan(90^{\circ}-75^{\circ})}{\tan15^{\circ}-\tan60^{\circ}}$ = $\frac{\tan60^{\circ}-\tan15^{\circ}}{\tan15^{\circ}-\tan60^{\circ}}$ = $\frac{-1(\tan15^{\circ}-\tan60^{\circ})}{\tan15^{\circ}-\tan60^{\circ}}$ = $-1$ Hence, the correct answer is –1.
