Graphing calculators are super expensive and you probably wouldn't need later on in life. It's best to use if you specifically need to calculate bell curves. However, that's just the whole function of the app - nothing else. Still super helpful and accurate though.

WebHere is an example of a flat-top or super gaussian: Currently the flatter the gaussian becomes, more and more information is lost, due to gaussian cutting down the edges.
