Mathematical knowledge needed for studying for a doctorate

If you are a doctor of arts, it is good to know advanced mathematics.

If you are a doctor of engineering, you should also be divided into majors. If the requirements are high, to reach the level of master of mathematics, you don't have a high understanding of professional mathematics.

If you are a doctor of science, such as physics, the level of mathematics directly determines your professional ability.
