Calc3 Assistant troch Omar Ramy

Calc3 Assistant is a browser extension that helps you solve multivariable calculus problems symbolically, directly in your browser. It supports partial derivatives, gradients, integrals, and more.

Calc3 Assistant brings advanced multivariable calculus tools to your fingertips. Using a clean and interactive interface, you can input expressions using familiar LaTeX-style math fields and receive symbolic solutions instantly. Powered by SymPy, all computations run locally in the browser — keeping your data private and eliminating the need for any server or internet connection after initial load.

Supported operations include:

Partial derivatives (with respect to any variable)

Gradients, divergence, and curl

Double and triple integrals

Line and surface integrals

Arc length and directional derivatives

Lagrange multipliers for constrained optimization


Built for students, engineers, and educators, Calc3 Assistant requires no setup — just open the extension and start calculating. Whether you're reviewing concepts, solving assignments, or checking your work, this extension saves time and adds confidence to your learning.
