Graphing Calculator Project
All plotting is done with a thousand increments. The f(x) function requires the use of JavaScript syntax such as Math.sin(x), Math.cos(x) and * for multiplication. The plot f(x) function creates an array of 1000 y/x slopes used with the f' (derivative) function. The area under the graph (integral) is the sum of 1000 riemann rectangles. Values are approximate and maybe wrong. Change the default settings and press either the plotf(x) button or the graph button.
