Welcome!

• MasterGrapher is an interactive function plotting program.

• Are you doing maths or science?

• Have you ever wondered what y(x)=sin(20*x)+sin(21*x) looks like?

• Mastergrapher can plot just about any normal 2D function, from y(x)=x+2 to y(x)=10^(sin(cos(x))/log(x^2)) on the screen for you right now while you are looking at this page.

• MasterGrapher is for students, teachers, even professionals who need to see what a certain function looks like.

... and of course it's absolutely FREE to use. Just click "Start MasterGrapher"!

How to use MasterGrapher

• Click the "Start MasterGrapher" button.

• MasterGrapher appears, with two example functions already drawn.

• Click on these two functions or click on an empty function box on the right hand side to display the "Function Editor" where you can Update, Delete or Add functions.

• Zoom by dragging a zoom-box over the region you want to zoom into. The scales on the axes can be set to anything you like by selecting "Scale Axes" from the "Options" menu.
