If 3\sqrt{3}3​ tanA = 3 sinA, find the value of (23cosec⁡A×tan⁡A)(2\sqrt{3} \cosec A×\tan A)(23​cosecA×tanA)​​
Question

If 3\sqrt{3} tanA = 3 sinA, find the value of (23cosecA×tanA)(2\sqrt{3} \cosec A×\tan A)​​

A.

6

B.

3\sqrt{3}

C.

232\sqrt{3}

D.

2

Correct option is A

Given: 

3\sqrt{3}​ tanA = 3sinA 

To find: (23cosecA×tanA)(2\sqrt{3} \cosec A×\tan A) 

Solution: 

3tanA=3sinA sinA=3tanA3  cosecA=33tanA\sqrt3\tan A = 3 \sin A \\ \ \\ \sin A = \frac{\sqrt3 \tan A}{3} \\ \ \\ \implies \cosec A = \frac{3}{\sqrt3 \tan A} 

Now, putting this into the expression;

23cosecA×tanA =23×33tanA×tanA =62\sqrt{3} \cosec A×\tan A \\ \ \\ = 2\sqrt{3}\times \frac3{\sqrt3\tan A}×\tan A \\ \ \\ = 6​​
