Draw a curve and find the best-fitting mathematical equation.
By default, the app opens in pure function mode, which means, you cannot draw functions that have more than one y-value for any given x-value (in other words, the curve cannot bend backwards towards itself). However, switch from Pure Function to Parametric, and you can draw even spirals!
By default, the app puts the origin on the bottom left corner, but you can switch it to the center, for example if you're looking to model an activation function of your chosen shape! In such cases, you should set the x and y bounds to 1x1 so that you get better resolution.
On the solve tab, you can play with the various function types - the suboptimal ones will be shown by default in dotted lines. You can also copy the formula in LaTeX or plaintext, and you can plot the function on WolframAlpha for tweaking the parameters more. Finally, you can also download the result as an image to include in a presentation, if you like. Tip: if you would like to avoid the dotted options, just pick the function class explicitly, and the dotted options will disappear.
