Have you mastered algebra and trig? If not, do it. Khan Academy is great for this. Watch the videos and do lots and lots of problems. In learning math, there is no substitute for working through lots of problems. After this, I suggest l

Also a missile's range and effectiveness depend upon both aircrafts' altitudes and velocities. Even if the predator could fire an AMRAAM, I don't think it would stand much of a chance of winning an engagement against a fight

Even in math "infinity" often means "unbounded". For example, in real analysis if we have a sequence x_n, we write lim x_n = ∞ to mean "given any real number alpha, we can find a natural number K, such that x_n &gt

How do you like working in OR? Are there a lot of jobs in the field? I'm a math major and like programming, so it seems like it'd be an interesting career for me.

It's not just cheating, it's also the fact that when you have to use automated grading, it's much more difficult to create good tests. I hope in the future they offer you the option of taking a real test at a testing center, which is graded

Would you mind sharing some more about how you got your first programming job? Did friends help you land the job, or did you just wow them in an interview? Did you have an impressive portfolio or degree?

I'm currently loving Jennifer Widom's DB class, and I'm excited about this and ML next quarter. I really hope this phenomenon spreads outside of their CS department; I'd love it if there were some pure math classes(like real analysis and ab

I'd also like to know which book. I just bought Strang's Introduction to Linear Algebra to study along with his video lectures. If it's based on this book I'd love to join.
