Graph points/equations using the xy-grids of the Scratch interface. - Please see the notes in the notes section below for more info. - Press right arrow at any time to switch backdrops. - When plotting an equation, you may press 'm' to show/hide variables in the equation. - Type in 'sohcahtoa' at any time (not when a question is being asked) to view the relationships between the equations y = x sin(θ) (red), y = x cos(θ) (green) and y = x tan(θ) (blue) across 360 degrees. Note that this will clear all equations and points currently graphed.
Notes: - Since the graph is based on the x-y coordinates of the Stage, you'll have to use big numbers. - The (square) brackets in y = log[a](x - b) means base-'a' logarithm of (x - b) eg. log[2](x) = base-2 logarithm of x. - Don't forget to use decimal numbers! There are times when these will really come in handy, such as y = (0.2)(x + 50)^2 + 20
