    Programming trignometry in assembly language

    Hello. Is it possible anyone here could help me with my problem?

    I'm doing a little assembly language programming for an old processor. But because it's old it doesn't have any instructions for performing anything but basic functions.

    Could somebody please explain how I could work out things like Sine, Cosine and Tangent functions, when all I can do is add, subtract, multiply and divide?

    Any help or pointers would be much appreciated.

    Thank you in advance.
