CalcVert: Calculator Converter

CalcVert combines a calculator, scientific calculator, graphing calculator and unit converter in one clean, easy-to-use app for everyday math, school, study and work. Solve equations, inequalities and systems with step-by-step solutions, use advanced math functions, plot interactive graphs, convert units and currencies, and understand how calculations work. Equation & Inequality Solver Solve linear, quadratic, rational (fractional) and higher-degree equations and inequalities, depending on the expression. Get clear results in mathematical notation, with detailed solution steps to help you understand the process. • Step-by-step solutions Follow the reasoning behind each problem. For supported expressions, explore multiple solution methods, including sign analysis, isolating squared terms and the quadratic formula (discriminant). • Solution sets View inequalities using interval notation and equivalent conditions, such as: (-∞, -3/2] ∪ (-1, 1) or x ≤ -3/2 or -1 < x < 1. • Systems solver Solve systems with two or more expressions, including equations and inequalities, with steps for supported problem types. Calculator • Everyday calculator Perform addition, subtraction, multiplication and division with an intuitive interface. • Scientific calculator Calculate powers, custom exponents, square and cube roots, nth roots, reciprocals, logarithms (log and ln), and expressions with π and parentheses. • Trigonometry Use sin, cos, tan, arcsin, arccos, arctan, sinh, cosh and tanh in degrees or radians. Graphing Calculator Plot and analyze functions and conic sections, including lines, parabolas, circles, ellipses and hyperbolas. Display multiple equations on the same Cartesian plane. • Graph analysis Explore intercepts, intersections, vertices, foci, axes, directrices, minimum and maximum points, asymptotes, symmetry and other curve properties. • Dynamic parameters Enter equations with variables, such as y = mx, and change parameter values to see the graph update as a line rotates or a curve changes. • Graph recognition Identify supported graph or equation types in the current view and inspect detailed properties. Projects and Export Name and save graphing projects to continue later. Export and share .calcvert project files or save graphs as PNG images.
