How it works

You record the class once and review it little by little.

1

Record the class

With your phone or a recorder.

Record your classes only with your teacher's permission.

2

Test me

A short test on the whole class.

3

Today's review

A few minutes a day.

Checked formulas, with the minute in the recording

Each formula is checked automatically.

What You Record
"...so AB, the product, where AB sub I J equals the sum from K equals 1 to N of A I K times B K J..."

"...and then the transpose, A transpose I J is equal to A J I..."

"...the integral of one over X squared minus one DX..."
What You Get
Matrix Multiplication:min 04:12
\[(AB)_{ij} = \sum_{k=1}^{n} a_{ik}b_{kj}\]
Transpose:min 06:47
\[(A^T)_{ij} = a_{ji}\]
Integration:min 31:05
\[\int \frac{1}{x^2-1}\,dx = \frac{1}{2}\ln\left|\frac{x-1}{x+1}\right| + C\]
