The liberal arts questions in the college entrance examination are generally as follows

Trigonometric function (simplest), vector (not difficult), solid geometry, sequence, derivative, analytic geometry.

Personally, I think that liberal arts mathematics is mainly about calculation and reading, and it must be done too carefully, and generally it will not be too bad in the exam.

Formulas can be memorized properly, but it seems useless to memorize too much.

Be sure to do more questions and get 140+ for the finished papers.

So there is no big problem with liberal arts mathematics.
