If `sinA=3//5 andcosB=9//41,` where `A,B` are both in the first quadrant, then `sin(A-B)=……`

If sinA=3/5 and cosB =-12/15 , where A and B both lie in second quadrant, then find the value of sin(A+B).

If sinA=3/5 and cosB =-12/15 , where A and B both lie in second quadrant, then find the value of sin(A+B).

sinA. sin(A+B)=

If sinA=3//5,cosB=5//13 & A,B are acute, find sin(A+B)

If sinA=3//5,cosB=5//13 & A,B are acute, find sin(A+B)

If sinA = 3/5, cosB = 12/13, where A and B both lie in second quadrant, then the value of sin (A + B) is -

If sin A=(12)/(13), cos B= (3)/(5) and neither A nor B is in the first quadrant, then find the quadrant in which A+B lies.

If sin A=3/5, cos B=-(12)/(13),\ w h e r e A and B both lie in second quadrant, find the value of sin(A+B) .

If sin A= 4/5 and cos B =- 12/13, where A and B lie in first and third quadrant respectively, then cos (A+B)=
