I need help in this Trignomery proving question :-

ISC CBSE Class xi simple Trignomery proving question solved 779a1bf8-9343-4438-8612-f768bec405e2

for the numerator use


sin C - sin D = 2 cos((C+D)/2)sin((C-D)/2)


for denominator use


cos C+ cos D= 2cos((C+D)/2)cos((C-D)/2)

Very Happy LHS = 2sinx.co6x/2cosx.co6x
= sinx/cosx = tanx
