Sina + sinb = 1/3
2sin(a+b/2) cos(a-b/2) = 1/3...(i)
cosa + cosb = 1/4
2 cos(a+b/2) cos(a-b/2) = 1/4....(ii)
dividing (ii) by (i)
tan(a+b/2) = 4/3
sin(a+b) = [2tan(a+b/2)] / 1+ tan²(a + b/2)
= [2×4/3] / 1 + (16/9)
= (8/3 )/( 25/9)
= 24/25
2sin(a+b/2) cos(a-b/2) = 1/3...(i)
cosa + cosb = 1/4
2 cos(a+b/2) cos(a-b/2) = 1/4....(ii)
dividing (ii) by (i)
tan(a+b/2) = 4/3
sin(a+b) = [2tan(a+b/2)] / 1+ tan²(a + b/2)
= [2×4/3] / 1 + (16/9)
= (8/3 )/( 25/9)
= 24/25
