    Hmm... not very well then. cos(90) according to your parser is like -.447.... when the answer is actually 0. Same with sin.

    Radians...
    The word rap as it applies to music is the result of a peculiar phonological rule which has stripped the word of its initial voiceless velar stop.

    So you can use pi, then?

    Do you just type in "pi," or what?

    Um, I could define pi as a variable I suppose.

    Here, I'll put some variables in there that you guys can mess with.

    I have defined a few variables for you to mess around with now: x, y, pi (const at 3.14159265), and array (a 25 value array).
    Example: sin(pi) or array[3]=x
    Variable values are kept between operations. So if you do array[3]=5 in one statement, the next time you call array[3], it will still be 5, assuming no one else changed it.
    There we go:

    x
    y
    array[25]
    pi (const)
