sin (x + y)
= sin x cos y + cos x sin y
=1/2 +1/4
= 3/4
sin (x - y)
= sin x cos y - cos x sin y
=1/2 -1/4
= 1/4
x + y = arcsin (3/4)
x - y = arcsin (1/4)
2x = arcsin (3/4) + arcsin (1/4) -> x = 31.5 degrees
2y = arcsin (3/4) - arcsin (1/4) -> y = 17.1 degrees
= sin x cos y + cos x sin y
=1/2 +1/4
= 3/4
sin (x - y)
= sin x cos y - cos x sin y
=1/2 -1/4
= 1/4
x + y = arcsin (3/4)
x - y = arcsin (1/4)
2x = arcsin (3/4) + arcsin (1/4) -> x = 31.5 degrees
2y = arcsin (3/4) - arcsin (1/4) -> y = 17.1 degrees
