Scientific Calculator

Die Beschreibung von Scientific Calculator

Site Editorial Commentary：A powerful scientific and graphing calculator with matrices and complex numbers.

This free Scientific Calculator is a powerful tool designed to handle a wide array of advanced calculations with ease. Its intuitive and user-friendly design ensures a seamless experience, making complex computations accessible to everyone.

The calculator encompasses all the standard functions expected of a scientific calculator, along with advanced features such as complex number operations and matrix calculations. Experience super-fast algorithms that enable real-time scrolling and zooming of 2D and 3D graphs using the touch-sensitive screen.

Key Features:

* Graph implicit equations in 2 and 3 dimensions (e.g., x²+y²+z²=5²).
* Graph inequalities in 2 dimensions (e.g., 2x+5y<20).
* Graph functions of a complex variable.
* Display up to 5 graphs simultaneously on the same screen.
* Active analysis of functions for improved graphing of 2D functions with singularity points (e.g., y=tan(x) or y=1/x).
* Find Intersections on 2D graphs.

Personalize your experience by customizing the screen colors, background, and individual buttons to suit your preferences.

A fully ad-free version of this app is also available for an uninterrupted experience.
