About us
Graphing Calculator is a free set of browser math tools. You open a page, type an expression or matrix, and get a clear result without installing software or creating an account.
Our Story
We started this project because plotting a function for class or homework should not mean fighting desktop installs, licenses, or sign-up walls. Early on we shipped a focused graphing tool in the browser. People used it, asked for more, and we grew the site into a small toolkit around the same idea: useful math, available immediately.
Today the site covers interactive graphing for functions of x and a matrix calculator for common linear algebra work. The product still runs in your browser. Your inputs stay on your device unless you choose to share a link.
Who We Are
We are an expert team of engineers and mathematicians. We design the tools, write the math paths, and check results against known cases before features go live.
That review covers sample plots, derivative overlays, slider ranges, matrix operations, and exports. If a curve looks wrong or a step in a matrix result does not add up, we treat it as a bug and fix it. We would rather ship fewer features than leave unchecked math in front of students and teachers.
What We Do
We build and maintain free online calculators for graphing and linear algebra. The graphing calculator plots functions as you type, adds parameter sliders, can overlay derivatives, shows a table of values, and exports PNG, SVG, or CSV. The matrix calculator handles everyday linear algebra tasks such as determinants, inverses, and factorizations, with step-by-step explanations where we show them.
We use open libraries for evaluation and interactive graphics, including math.js and JSXGraph, so the tools stay transparent and light enough for phones and laptops. There are no ads and no forced accounts on the calculators. Questions about the product, the domain, or partnerships can go through our contact form or email.
If something looks off in a graph or matrix result, tell us. We check this work carefully, and reports from people who use the tools every day help us keep it honest.
