Scientific Calculator

Scientific calculator with graphing, calculus and matrices in a mobile-size floating window. Offline calculations and free themes.

Solve equations, explore graphs, perform arithmetic operations, and tackle advanced calculus using our Casio-Styled Scientific Calculator FX-991EX. From fractions and complex numbers to matrices, statistics, and double/ triple integration, access the tools you need for everyday calculations and engineering coursework. Developed from my engineering experience, this app brings scientific calculations, dedicated modes, and 2D/3D graphing together in a familiar calculator-style interface with a natural math display. Let’s delve into some of the features of the calculator: 1. Scientific Calculations: This calculator can easily perform basic scientific calculations such as fractions, powers, roots, logarithms, trigonometric and hyperbolic functions, and complex numbers. 2. Matrices and vectors: This calculator supports matrices and vectors. Each function has its own modes to perform the required calculation. It supports basic matrix and vector arithmetic operations, including transpose, inverse, magnitude, three-vector operations, and many more. 3. Statistics: This calculator is designed to take input in discrete, repetitive, and grouped data. From the input data, it can calculate basic statistics such as mean, median, mode, standard deviation, variance, linear regression, and advanced regression such as quadratic regression, cubic regression, log/exponential regression, and more. 4. Functions, equations, and polynomials: These features include table generation by inputting functions with variables, similar to the FX-991EX, solution of two/three variables simultaneous equations, and calculating the roots of polynomials. 5. Calculus and Graphing: For calculus, separate limit, derivative, and integration modes are given inside the calculator. For differentiation, the calculator supports ordinary derivatives, partial derivatives, implicit/parametric derivatives, and more. For integration, this calculator can perform double and triple integration. It can also provide 2D graphs of linear, polynomial, trigonometric, logarithmic, and exponential functions, with and without domain restrictions. 6. User Interface: This calculator interface is inspired by the FX-991EX. The “Options” key is available in every mode to find the required operation. Each calculation and result is displayed on its own natural math display. The calculator also includes many themes, including designs from classic calculators like Classic MS, and Classic IIS. Similarly, other Casio-styled themes are: 1. Scientific Calculator FC991EX 2. Scientific Calculator Fx991ES Plus 3. Ti-84 Plus CE Python and many more We can’t wait for you to try many other features.
