I'm a physics major in calc 3 and matrix theory and i'm finding math harder to learn than physics. My major requires calc 1-3, and differential equation. Matrix theory isn't hard but i do find that i need to spend much more time on math to be able to learn it than with physics where it comes to me much easier and makes more sense. Seeing that Physics is a pretty math intensive field, especially with theoretical physics, i was wondering how much math i really need? I do plan on getting a Ph.D in Physics and i don't want my math skills to hold me back but i don't enjoy learning math and it makes my schoolwork much more time consuming. Other math classes above diff. eq. are classes that deal with proofs, partial diff. eq 1 and 2, and then mostly theory classes after that. Are those necessary for me to take?
