How to describe a monomial in regular expressions?

Question

Mathematics

I study at school, I got carried away with programming in C#. To develop the skill, I want to write an application that will solve different types of equations, reading them from the input string. Faced with the fact that it is necessary to describe a monomial in the language of regular expressions, taking into account the fact that it can be a sine, and a square, and a logarithm, and a square of a logarithm, etc. When I tried it myself, the expression grew to such a size that I'm confused about it myself. I think that the task is typical and there are already solutions, but I could not find them in Google. Maybe actually in C # there is something.

You don't really need to use regular expressions for this kind of task.
