Introduces ordinary differential equations, systems of linear equations, matrices, determinants, vector spaces, linear transformations, and systems of linear differential equations. Prereq., APPM 1360 ...

She’s right—using simultaneous equations does get really complicated, and if you’d like to send me your work for the solution, I’d love to see it. But the system is also kind of a trick. Like a sudoku ...

Most linear algebra courses start by considering how to solve a system of linear equations. \[ \begin{align} a_{0,0}x_0 + a_{0,1}x_0 + \cdots a_{0,n-1}x_0 & = b_0 ...

Math equations can feel like a banal abstraction without images to make sense of the strings of numbers, letters, and Greek symbols. Consider the Pythagorean theorem, an essential relation in geometry ...

The confusion (likely intentional) boiled down to a discrepancy between the math rules used in grade school and in high school. By Steven Strogatz Recently I wrote about a math equation that had ...

One of my first vivid memories of math is of timed tests. I still remember how visceral my panic felt–sweaty palms, heart pounding–as I scrambled to recall facts before the clock ran out. You might ...

For almost two centuries, mathematicians believed there was no general solution for certain high-degree polynomial equations. Now, two Australian researchers—Norman Wildberger and Dean Rubine—have ...
