Physics is to write formulas first, then answers, and not even equations. For example: v=a*t, (start a new line) v=**. Don't write v=a*t=**, so you can get a lot of formula points for nothing every time. Even if the answer is wrong, the formula will give points, but if you wait, the formula points will be deducted.

Physical equation is the main body of expression. How to write, we should pay attention to the following points:

① The written equation (which is the basis of grading) must be the most basic, and the equation cannot be replaced by the deformed result formula.

(2) use letters to represent equations, don't mix equations with numbers, and don't set equations.

③ The original equations should be used for simultaneous solution, and some contents should be "continued" continuously, instead of simultaneous equations.

(4) If there are multiple equations, they should be divided into different types (graded step by step). Don't write a type together, so as not to make a mistake and cause a total mistake. Number all the programs (such as ①, ②, ③ for calculation and explanation).

Mathematical physics method is an important compulsory basic course for undergraduates majoring in physics, and also an important public basic course for majors such as marine science, mechanics, electronic information science and material science. Based on advanced mathematics and general physics, this course focuses on the common methods in classical mathematics and physics, and introduces the new development in recent years appropriately, so as to prepare for the subsequent related professional courses. Therefore, this course is highly valued by students.
