Mark the Correct alternative in the following:
If sin α + sin β = a and cos α – cos β = b, then
Given, sin α + sin β = a and cos α – cos β = b, then the value of
Consider sin α + sin β = a
As per the expansion of
Now , ----- (1)
Similarly, cos α - cos β = b
As per the expansion of
Now ------ (2)
By dividing equation (1) with (2) we get,
[As ]
Therefore the answer is option B.
