We partner with university mathematics and statistics departments to transform static PDF syllabi into living, interactive digital infrastructure.

"The medium is the message. A static medium teaches a static science."

— Marshall McLuhan

"Traditional statistical education relies on a broken medium. Students are handed static PDFs containing complex derivations, and expected to build dynamic, multidimensional intuition from flat text."

— The Editorial Board

Demonstration

We take your existing lecture notes, problem sets, and syllabi, and re-engineer them into browser-native interactive experiences.

Static Past vs. Live Future

Scroll down to watch static PDF derivations wake up and physically transform into live, interactive learning components.

Chapter 1: Probability Density

If $F_X(x)$ is the cdf of a continuous r.v. $X$ , its derivative is called the probability density function (pdf):

f_X(x) = \frac{d}{dx} F_X(x)

Which implies the Fundamental Theorem relationship:

F_X(x) = \int_{-\infty}^{x} f_X(t)\,dt

The PDF is not a probability. $f_X(x)$ can exceed 1. What must equal 1 is the total area under the curve.

F_X(x) = \int_{-\infty}^{x} f_X(t)\,dt

Chapter 2: Deriving the CDF

To find $F_X(x)$ , we integrate the piecewise density function $f_X(t)$ from $-\infty$ to $x$ across all three mathematical regions.

F_X(x) = \begin{cases} \int_{-\infty}^x 0\,dt & x < 0 \\ F_X(0) + \int_0^x \frac{1}{2}t\,dt & 0 \leq x < 2 \\ F_X(2) + \int_2^x 0\,dt & x \geq 2 \end{cases}

F_X(x) = \begin{cases} \int_{-\infty}^x 0\,dt & x < 0 \\ F_X(0) + \int_0^x \frac{1}{2}t\,dt & 0 \leq x < 2 \\ F_X(2) + \int_2^x 0\,dt & x \geq 2 \end{cases}
