The Tangent function is capable of producing these perplexing designs as shown here. I'll call them waterfalls since it looks like the clones of Scratch cat are falling from above like rain, getting stuck on a cliff, and then falling off of the cliff in a graceful way as a waterfall does. Parent Function: y = tan(t) t = time. Child Function: y = { a * [ ( tan ( ( p + ts ) * f) ) -1 ] * -1 } - a y is y position a is amplitude tan is the abbreviation for tangent p is timer addon t is time s is speed f is frequency
