Use Arrow keys to move around the graph. Space to make a line with the formula of y=mx+c. I actually made a function for parabola and cubic graphs and more but I plan on adding it later. I will try to make more functions like derivation and integrations, turning point and gradients and in-built fraction maker so you don’t have to use decimals. I will also make the function to make graphs of higher order, but I will need to improvise the derivative calculator for this. Don’t get me started on integrations. I will maybe try to make equations with x as the subject, but I don’t think that is my priority.
