About

Calculus & Probability Lab

Features
Read full description

Calculus & Probability Lab turns two of the hardest STEM subjects into something you can see, touch, and drag with your finger. Instead of static graphs in a textbook, every derivative, integral, and probability distribution becomes a real 3D object you orbit, zoom, and reshape live. Whether you're in AP Calculus, a first-year college calculus or statistics course, or just relearning math you forgot, this app trades memorized formulas for visual intuition: drag a point along a curve and watch its tangent-line slope update instantly, or watch a histogram built from real dice tosses close in on the bell curve as you roll. FUNCTION LAB β€” 3D VISUALIZER β€’ 22 function families: lines, parabolas, cubics, quartics, sine/cosine waves, exponentials, natural logs, reciprocals, square roots, Gaussian bumps, logistic S-curves β€’ Genuine z = f(x, y) surfaces β€” paraboloids, saddles, Gaussian hills, ripples, sphere caps, cones, tilted planes, monkey saddles, egg-carton surfaces, twin peaks β€” drag to orbit, pinch to zoom β€’ Live tangent-line overlay β€” move a point along any curve and watch the exact derivative f'(x) recompute in real time β€’ Riemann sum overlay β€” slide from 1 to 60 rectangles and watch the sum converge to the exact definite integral β€’ Every formula is closed-form and exact β€” no approximation, no drift PROBABILITY LAB β€” PHYSICS DICE β€’ Toss physics-simulated dice and build a genuine empirical histogram, roll after roll β€’ Scenarios span dice-sum outcomes, coin-flip binomial trials, and Poisson arrival processes β€’ Overlay your empirical results against the exact theoretical distribution on the same chart β€’ Watch the Central Limit Theorem happen live: enough trials and the histogram closes in on the normal curve β€’ Track empirical mean against theoretical mean at every roll LEARNING PATH β€” 4 WORLDS, ~50 LESSONS β€’ World 1, Functions & Limits: what a function is, families of functions, slope, one- and two-sided limits, continuity, average vs. instantaneous rate of change, exponentials and logs β€’ World 2, Derivative Lab: the derivative as slope, power/product/quotient/chain rules, higher derivatives, tangent planes and partial derivatives, critical points, related rates, optimization, the Mean Value Theorem β€’ World 3, Integral Lab: area under a curve, Riemann sums, the definite integral, antiderivatives, the Fundamental Theorem of Calculus, net change, average value, area between curves, volumes of revolution, improper and numerical integration β€’ World 4, Probability & Distributions: sample space and events, combining probabilities, the two-dice sum, random variables, expected value, binomial and Poisson models, the normal curve β€’ Every lesson deep-links straight into the matching 3D lab, so theory and visualization reinforce each other AI TUTOR β€’ Tap Explain on any surface, formula, or dice distribution and get a plain-language breakdown of exactly what's in front of you β€” your specific coefficients, your specific slope, your specific mean and standard deviation, not a generic textbook definition BUILT FOR REAL STUDY, NOT JUST BROWSING β€’ Progress tracking across every world and lesson, so you always know where you left off β€’ A limited number of dice rolls each day on the free tier; upgrade to roll without limits, unlock every function family and 3D surface, every lesson, and the AI tutor β€’ A clean, dark, distraction-free interface built for a late-night study session, not a cluttered graphing-calculator UI β€’ Monthly and Annual plans, with a 3-day trial on Annual β€” cancel anytime in your account settings Calculus and probability are usually taught as two separate walls of formulas to memorize before an exam. Calculus & Probability Lab treats them as one connected, visual subject β€” build the intuition once, and the formulas stop needing to be memorized at all.
