Question

cos 3x = 4 cos' - 3 cos​

Answer 1

Answer:

If A,B are acute angles,sinA=4/5,tanB=5/12,then cos(A-B)=

Step-by-step explanation:

If A,B are acute angles,sinA=4/5,tanB=5/12,then cos(A-B)=If A,B are acute angles,sinA=4/5,tanB=5/12,then cos(A-B)=If A,B are acute angles,sinA=4/5,tanB=5/12,then cos(A-B)=

If A,B are acute angles,sinA=4/5,tanB=5/12,then cos(A-B)=If A,B are acute angles,sinA=4/5,tanB=5/12,then cos(A-B)=MAA CHUDA
