Lexer grapher and multiplication symbol

[AIPAL18]

Describe the bug

When typing the expression x=((2v^2(cos(a)sin(a)-cos(a)^2sin(u)))/10) in the grapher, the calculator complains about a syntax error. But when I add the multiplication symbols, it works. Which I find peculiar.

Screenshots

To Reproduce

Steps to reproduce the behavior:

1. Go to the grapher
2. Type x=((2v^2(cos(a)sin(a)-cos(a)^2sin(u)))/10)
3. See syntax error

Expected behavior

I expected that I would not need to add the multiplication symbols, as the calculator would remove them automatically.

Environment

• 24.10.0
• online simulator and actual device

Thanks for reporting this !
This is probably because v is reserved for the sequence in our parser
A simplified version of the formula: x=v^2(1) fails to parse whereas x=b^2(1) works fine

So for now you could just rename the variable v to be something else, like b
