    Trigonometric Functions?

    Example:
    Code:
    sin(90-x) = cosx
...
tg(270-x) = ctgx
...
etc.
    Where can i get info (like a table) with all these functions (sin(180-x) = ?, cos(360-x) = ?,tg(270-x) = ?), etc.
    I am become death, the destroyer of worlds.

    There's a lot of info on them in the VB help files for trig functions. Someone pasted a load of info on them a few weeks ago.

    you'll find this kind of stuff in all better general math books. and if you are too lazy to go to library check:

    Look up 'derived math functions' in vb help, for instance. Not every possible trig function is supported by the math library of every language. In this case, help tells you which identity to use for an unsupported trig function. Or other function.

    ... just an aside.
