graphing

hello this is a project that graphs stuff cool. how do i add new lines?

oh that makes sense

in case you don't know what an equation is, here is an example: "5=2+3." but for this project it graphs equations, so you need to write "y=(expression)." to make a line that goes at a 45 degree angle, write this: "y=2*x". try experimenting with other equations!

some built-in functions includes: sin, cos, tan, asin, acos, atan, atan2 (what lol), ln (natural log), log, rt (stands for root i probably should have put rad or something). also includes constants like e and pi
