Built for the way NEET, JEE, and IGCSE students actually calculate day to day, with degree/radian switching, memory functions, and a running history you can revisit mid-problem.
No downloads, no sign-up — just open it and start calculating.
- Trig, log, power, root & factorial functions with DEG/RAD toggle
- "How it's solved" panel breaks down every calculation step by step
- Memory recall, calculation history, and full keyboard support
- Instant, in-browser, completely free
SWETAxAI Mathematics Formula Finder - Virtual Tools · Free
128 formulas across 12 topics — Algebra, Geometry, Trigonometry, Coordinate Geometry, Calculus, Statistics, Commercial Math, Sets & Functions, Complex Numbers, Matrices, and Vectors — searchable, organized, and explained in plain language.
But it's more than a reference. 88 of these formulas come with a live calculator built right in: type in your own a, b, and c and watch the quadratic formula solve your actual problem, roots and all. Same for Heron's formula, HCF/LCM, permutations and combinations, matrix determinants, vector cross products, and dozens more — plug in numbers, see the working, get the answer.
Search by name or keyword, filter by topic, star your most-used formulas for quick access, and check the daily "Formula of the Day" spotlight.
Built for CBSE, IGCSE, JEE, and NEET syllabi — no downloads, no sign-up.
- 128 formulas across 12 topics, from Grade 6 through JEE/NEET level
- 88 live calculators — enter values, get a worked answer
- Instant search, topic filters, and a session favorites list
- Instant, in-browser, completely free
SWETAxAI - Function Transformation Explorer Virtual Math Lab · Free
Nine parent functions — x², x³, √x, |x|, 1/x, sin x, cos x, 2ˣ, log₂x — and four live sliders that let you see, not just memorize, how a, b, h and k reshape a graph.
Drag "a" and watch the curve stretch, compress, or flip across the x-axis.
Drag "h" and "k" and watch it slide across the plane. As you move, a plain-English readout updates in real time — "Reflected across the x-axis," "Shifted right 3 units" — so the connection between the numbers and the shape is never left for you to guess.
When you're ready to test what you've learned, switch to Challenge Mode: match a target graph using only the sliders, and get instant feedback on how close you are.
- 9 parent functions spanning algebra, trigonometry, and exponentials/logs
- Live equation display that updates with every slider move
- Plain-English transformation breakdown — no guessing what changed
- Challenge Mode to test your understanding, not just your memory
- Instant, in-browser, completely free
SWETAxAI - Standard Deviation Calculator Virtual Math Lab · Free
Type in a data set and watch the calculation build in front of you — mean, deviations, squared deviations, and the final standard deviation, one step at a time. No black-box answers, just the full working shown live.
A step-by-step table tracks every value through the process, while a five-step formula walkthrough carries the same numbers from x̄ = Σx/n all the way to σ = √σ². A number-line visualization plots your actual data points against shaded ±1σ and ±2σ bands, so "spread" becomes something you can see rather than just calculate. Toggle between Population (σ) and Sample (s) modes with plain-language guidance on which one your data calls for.
Six preset data sets — including a deliberately tight "low spread" set and a wide "high spread" set — help you build intuition for what different standard deviations actually look like.
When you're ready to test yourself, Practice Mode generates a fresh problem with a self-check answer key.
- Live step-by-step table and 5-step formula walkthrough
- Number-line visualization with mean and ±1σ/±2σ bands
- Population and Sample modes, explained in plain language
- Practice Mode for self-testing after you've learned the steps
- Instant, in-browser, completely free
