You said it before I could!  After I posted that, I thought the same thing. Both are excellent.

After screwing up Trig-Analytic Geometry in 12th grade, I grew fearful of math.  I was doing great until I got halfway through.  Then, I was sooo freaking lost. I really need to go back and re-learn that stuff.  I think I'll make that my next goal.  My highest math was Calc 2.  I even figured out how to use it in various applications.  I have watched videos on Matrices and Differential Equations.   I really do need to plug my Trig-Analyt hole, though.

If you were doing problems in Diff equations, then you have what it takes for advanced math.

My favorite was topology. That is more pure math than applied math. Though it does have some fantastic applications. Check it out - in topology, a math professor proved that you could turn a sphere inside out without cutting a slit in the sphere. That is to say, if you had a tennis ball, and the ball was made of zero resistance malleable material, then it is theoretically possible to turn it inside out without cutting a slit in it. That blows my mind.
