For the new college entrance examination, there is no difference between liberal arts mathematics and science mathematics, but for the new curriculum standard, liberal arts mathematics and science mathematics are different. The specific differences are as follows: liberal arts mathematics does not test dihedral angle, distribution list expectation, independent event probability calculation formula, binomial distribution, hypergeometric distribution and normal distribution. Because liberal arts mathematics solid geometry does not test dihedral angle, so the second question usually tests volume or distance, and this science can only test one option to fill in the blanks. Distribution table and mathematical expectation belong to the content of probability theory and mathematical statistics, which are involved in the courses of probability theory and mathematical statistics in high schools and universities. It belongs to mathematics, and there are certain designs in both science mathematics and liberal arts mathematics, but science mathematics is deeper and liberal arts mathematics is simpler.
