Courses in applied mathematics that are essential for studying physics include a complete calculus sequence (including multivariable calculus), linear algebra, and differential equations. These foundational subjects are critical across various branches of physics. Additional beneficial courses include differential geometry, tensor analysis, complex analysis, boundary value problems, calculus of variations, and waves/oscillations. While these advanced topics enhance understanding, the core requirements generally suffice for undergraduate studies. Statistics courses tailored for science and engineering, along with numerical methods, are also recommended. Some graduate-level physics courses may require knowledge of contour integrals, highlighting the importance of complex variables and numerical analysis in solidifying scientific computing skills. Overall, a strong mathematical background significantly aids in the study of physics.
