A little "coding doodle," as I call it, after my trigonometry chapter in pre-calculus. Trigonometry is one of the few math topics I can safely say I'm good at, and I wanted to do something useful as my first project in scratch 3.0. The available graph types are sin, cos and tan. Input one of them at the start. General Variable Guide: a = amplitude (maximum deviation from the midline) b = affects period (one full pattern) c = affects phase shift d = midline Press [E] to reset your drawing and input another graph. I'll possibly add in cosecant, secant and cotangent graphs, as well as all six arc functions in the future.
