it works now!! press space to enter an equation however there are some rules: no implied multiplication, like 3x or (10+2)(4-5), instead 3*x or (10+2)*(4-5) also no negatives like 3*-1 instead 3*(0-1) if you do, the computer will probably crash, or just freeze cuz unfortunately i couldnt figure it out just type "x" as the variable, so you dont gotta type in theta, its easier on the grapher
