[" If "sin x=(12)/(13)" and "sin y=(4)/(5)," where "(pi)/(2)

if sin x=(12)/(13) and sin y=(4)/(5) find the values of sin(x+y)

If sin A=(12)/(13) and sinB=4/5 , where pi/2 lt A ltpi and 0 lt B lt pi/2 find the following : sin(A+B)

If sin x = (15)/(17) and cos y = (12)/(13),0 lt x lt (pi)/(2) , 0 lt y lt (pi)/(2) , find the values of sin (x + y)

if sin x=(3)/(5),cos y=-(12)/(13) where (pi)/(2)

"if y"="cos"^(-1)((5"cos" x-12 "sin"x)/(13)), where x in (0,(pi)/(2)) , " then "(dy)/(dx) " is"-

If sin ^(-1) ((5)/(x)) + sin ^(-1) ((12)/(x)) = (pi)/(2), then x is equal to: A) 7/13 B) 4/3 C) 13 D) 13/7

sin A = (12) / (13), cos B = - (3) / (5); 0

show that sin ^(-1)""(4)/(5) +sin ^(-1)""(5)/(13) +sin ^(-1)""(16)/(65) =(pi)/(2)

y(dy)/(dx)sin x=cos x(sin x-(y^(2))/(2)); where at x=(pi)/(2)
