Advanced Calculus Plus

Advanced Calculus Plus turns your phone into a complete scientific workbench for anyone who thinks in equations, functions, and formulas. Whether you're checking homework, exploring how a function behaves, or converting units on the fly, Advanced Calculus Plus keeps every tool a single tap away. Start with a full scientific calculator featuring trigonometric and inverse trigonometric functions, logarithms, and a running calculation history you can revisit, copy, or clear anytime. Move to the Graphing screen to plot functions on an interactive canvas — zoom in, pan around, and trace exact coordinates along the curve as you explore it. Need calculus? The Calculus Tools screen finds derivatives at a chosen point using a central-difference method and evaluates definite integrals with Simpson's rule, so rates of change and areas under curves appear instantly. To solve fCross Mark = 0, the Equation Solver offers both the Bisection method and Newton's method, with adjustable tolerance for precision. Handle linear algebra with the Matrix Calculator, covering addition, subtraction, multiplication, and determinants. Store your own constants and results for reuse with the Variables screen, saving named values or expressions like 2*pi and calling on them from every other screen. A built-in Unit Converter covers length, mass, temperature, volume, and time. Every screen shares your saved variables and respects your preferred angle mode — degrees or radians — along with your chosen decimal precision, set once during a short onboarding walkthrough or adjusted anytime in Settings. Pick between a bold amber-on-dark theme or a clean light layout to match how you like to work. Built for students, engineers, and anyone who wants serious math tools without a cluttered interface, Advanced Calculus Plus brings calculators, graphs, derivatives, integrals, equation solving, matrices, and unit conversion together in one focused, fast app.
