Question 2

Time: 00:00:00



If cos X = m cos Y and where X and Y are not equal to each other and values of angle X and Y range from 0° to 90°, then 




cot (X + Y / 2) = [(m + 1) / (m – 1)] tan (Y – X / 2)
 

cot (X + Y / 2) = [(m + 1) / (m – 1)] tan (Y – X / 2)
 

tan (X + Y / 2) = [(m + 1) / (m – 1)] cot (Y – X / 2)
 

tan (X + Y / 2) = [(m + 1) / (m – 1)] cot (Y – X / 2)
 

cot (X + Y / 2)  = [(m + 1) / (m – 1)] tan (X – Y / 2)
 

cot (X + Y / 2)  = [(m + 1) / (m – 1)] tan (X – Y / 2)
 

cot (X + Y / 2) = [(m – 1) / (m + 1)]  tan (X – Y / 2)
 

cot (X + Y / 2) = [(m – 1) / (m + 1)]  tan (X – Y / 2)
