then b = sin-1(y) - a, where sin-1() is the Arcsin or Inverse Sin function.

Hi all! I'm backtesting a Pick 3 Strategy that (unfortunately) involves Trigonometry, and I'm stumped regarding a deceptively simple question that is making my backtesting extremely labor intensive. Any help would be greatly appreciated!

So . . . with b being the unknown . . . how the (insert your favorite expletive here) do you solve for b when you have sin (a + b)? I know the basic Trig equations sin(a + b) = sin a cos b+ cos a sin b and cos(a + b) = cos a cos b - sin a sin b, but beyond th... [ More ]
