If sin theta + sin phi = a, cos theta + cos phi = b prove that tan ((theta-phi)/2 )=pm sqrt((4-a^(2)-b^(2))/(a^(2)+b^(2)))
Angles In geometry, an angle is a shape that is created when two rays meet at a specific point. When we examine all the angles around that point, their combined sum is always equal to 360 degrees. This property is helpful when solving problems involving angles at a given point, as it ...
