माना कि `alpha` एवं `beta` इस प्रकार की अशून्य वास्तविक संख्याएँ (non-zero real numbers) हैं कि `2(cos beta - cos alpha) + cos alpha cos beta = 1` तब निम्न में से कौन सा(से) तथ्य है(हैं) ? 1-`sqrt(3) tan ((alpha)/(2)) + tan((beta)/(2)) = 0` , 2-`sqrt(3) tan ((alpha)/(2)) + tan((beta)/(2)) = 0` , 3-`tan((alpha)/(2)) + sqrt(3) tan((beta)/(2)) = 0` , 4-`tan((alpha)/(2)) + sqrt(3) tan((beta)/(2)) = 0`

A

`sqrt(3) tan ((alpha)/(2)) + tan((beta)/(2)) = 0`

B

`sqrt(3) tan ((alpha)/(2))-tan((beta)/(2)) = 0`

C

`tan((alpha)/(2)) + sqrt(3) tan((beta)/(2)) = 0`

D

`tan((alpha)/(2)) + sqrt(3) tan((beta)/(2)) = 0`
