About

1st Principle

Features
Read full description

1st Principle is a calculus platformer built on a live graph. You run and jump along y = f(x), and the derivative decides where you can stand: where the slope gets too steep, the path breaks into gaps and hazards. Every level turns an idea from math into something you can see and play. PLAY THE MATH – Platforms follow the curve and f′(x) shapes the gaps and hazards, so a function and its derivative stay connected in your head – 59 levels: parabolas, sine and cosine, Maclaurin and Taylor series, multivariable slices, area under the curve and Riemann sums, damped oscillation, polar roses, logistic growth, Fourier and Laplace transforms, Big O growth rates, aerospace and physics stories, and boss levels such as the Mandelbrot set and the Lorenz attractor – Earn up to three stars per level, beat your best score and unlock achievements – A daily challenge with goals and a streak to keep – Hints that explain the rule behind each level GRAPHING CALCULATOR MODE Switch to a free graph workspace from the menu: type an expression, adjust it, then zoom and pan (pinch on touch screens) to explore functions without the platformer. LEARN AS YOU PLAY An in-game reader covers differentiation rules, definite and indefinite integrals and topic glossaries, with short study notes for AP Calculus BC, AP Physics C, AMC 10/12, TMUA and MAT.
