SymCalc+2.2 - App Store

Solve equations, simplify algebra, take derivatives and integrals, work with matrices, and visualize results in 2D and 3D from one app.

Whether you need an exact symbolic answer, a decimal approximation, or a graph, SymCalc keeps the full workflow in one place. Store your work in reusable sessions, assign variables, define your own functions, and come back to your calculations later.

- Solve single equations and systems with exact or numerical results
- Simplify, factor, expand, substitute, and find roots, limits, sums, products, and Taylor series
- Handle calculus tasks including derivatives, indefinite and definite integrals, and differential equations
- Work with matrices and vectors: determinants, inverses, rank, RREF, eigenvalues, eigenvectors, dot products, and cross products
- Graph standard functions, implicit equations and inequalities, polar curves, parametric plots, and 3D surfaces
- Use logarithmic axes, inspect intersections, and adjust extra variables with sliders
- Compute with complex numbers and common scientific functions
- Save worksheets, keep multiple sessions, create custom functions, and export your work as PDF or SymCalc files
- Learn faster with built-in function help and examples inside the app
- Built for students, engineers, scientists, and anyone who needs more than a basic scientific calculator

Version History Major graphing upgrade:
- implicit equations and inequalities
- parametric curves
