Things I've written that are meant to help students.

Er, this is probably too late for most of the students revising for exams. Sorry, I forgot that happens this time of year. I used to be a good teacher, I swear!

If it isn’t too late, I hope these short posts make useful study aids:

• How to multiply matrices.
• Determinant of a matrix … what is it?
• Eigenvectors.
• What the heck are sine and cosine, anyway?
• How I finally came to understand the Pythagorean Theorem.
• The LaPlace Transform. (ODE class)
• Matrices (as transformations).
• How do you do integration by parts? (calc class)
• How can you tell whether a series converges? (calc 2) [a series = the sum of an entire sequence]
• Manifolds.
• A 1-D ODE / vector field as drawn by Robert Ghrist.
• Vector calc: Gauß’ divergence theorem.
• Positive semidefinite. (Hessians ‘n’at.)
• Jacobians

And a couple others for the kids who have finished their exams and are now letting the cram-packed study matter seep from their brains:

• The main takeaway from calculus.
• The chief triumph of the differential calculus.
• What’s the similarity between a quark and a Rubik’s cube?
• I only dated vegetarians until I learned regression analysis.
• Dungeons & Dragons and the Central Limit Theorem. (also known as the nerdiest thing ever which anyone will ever write, and I challenge you to top that)
• Does √−1 exist?

Supposed to be doing University work and I’m sitting here editing.
