Mathematical formulas for games

### Describe the project you are working on

2D platformer

### Describe the problem or limitation you are having in your project

Beautiful jumps and curves require mathematical formulas

### Describe the feature / enhancement and how it helps to overcome the problem or limitation

add to the documentation or manual a list of formulas that may be useful for beginners to improve the quality of games, It is possible to implement a special node of the curve by formula ?
creating curves in inspector is convenient, but the curve is not very precise, it is unclear how the curve should look for a specific animation (maybe add animation for the curve, as in the tutorial about curves, only in inspector)

### Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

When opening the documentation, the user searches for a formula in a separate page or creates a curve on a separate node

### If this enhancement will not be used often, can it be worked around with a few lines of script?

possible

### Is there a reason why this should be core and not an add-on in the asset library?

This way users can use the formulas more often, but also in the asset library it’s a good solution
