This function is supported by the calculator app and note app, so you can write formulas and draw an equal sign.
It recognizes the formulas I wrote and writes the answer on the left side in a font similar to handwriting (orange text in the photo).
As you can see in the picture, the units are written down, and the variables I specified seem to be recognized.
You can also express the formulas I wrote in a graph.
When you change the value of a variable, the shape of the graph changes in real time.
ex) If you tap 30º in the photo, a dial UI will appear, and if you turn the dial, the graph will change.
