I am a freshman Physics major and I always thought I would be required to learn a lot of higher level maths. But I picked up a major requirement sheet today and found out I only need to take the 3 level calc sequence, linear algebra, and DiffEQ. Thats it. Now I understand I CAN take more, and frankly I am pretty positive I will,especially considering by the end of this year I will have met all of those requirements except DiffEQ. But I am wondering, is this a normal range of mathematical requirement? Is it because beyond those sequences the higher level math you need depends on your area of your specialization? So in grad school are you ever in Physics classes that end up teaching you a lot of math concurrently? I'd hate to stop learning math past calculus... Thanks for any responses.
