parser

I am planning to build an expression parser that will be used to graph algebraic functions ( think TI-83 ) with JavaScript.

Functions will take the form of f(x)=

Aside from typical operators such as: + - * / ^

I'd also like to add support for inline functions such as: sin(), cos(), log() and random().

I have looked at implementing the Shunting Yard algorithm for parsing expressions, but it does not look like an efficient approach to evaluating a function with a hundreds or thousands of inputs. What other known algorithms exist for this task?
