How to calculate how far an object travels given the launch angle

I would like to be able to calculate how far something travels given the launch angle (assuming a constant force). I know already that launching an object at 45 degrees gives it the longest distance (let's call this distance "1") and that launching the same object at 60 degrees gives it distance 1/2.
However, I do not want the calculation to just be that. I want something for the whole entire 88 degrees (1-89). I don't want an array filled with numbers, I want an equation. And oh, this is in JavaScript, but that shouldn't really matter because this is an equation.

a = 45;

d = Math.sin(2*a*Math.PI/180);

60 won't go .5 it will go .866.
