Hello everyone! I just registered on this forum! I've been interested in astronomy and cosmology for quite a few years now, and I'm thinking of doing astrophysics. The only problem is: I'm not good at pure math. As long as I see the practical use of math, I'm quite good, but as soon as it becomes too theoretical, where I don't know how it could be of any use in practical work, I lose interest. Now my question is: are pure math skills (i.e. theorethical math) in astrophysics important? thank you!
