This scientific calculator provides a full range of mathematical functions beyond basic arithmetic, including trigonometric, logarithmic, exponential, and factorial operations. It supports parentheses for complex expressions, memory storage for intermediate results, and both degree and radian modes for angle calculations. The calculator handles constants like pi and the Euler number, and displays a history of your recent calculations for easy reference. Engineering students, science researchers, teachers, and professionals who need quick access to advanced math functions without installing desktop software will find this browser-based calculator both powerful and convenient.

Frequently Asked Questions

Is the AfroTools Scientific Calculator free to use?
Yes, the AfroTools Scientific Calculator is completely free with no sign-up required. It includes trigonometry, logarithms, memory functions, constants, and full keyboard support at no cost.
Does the scientific calculator work offline?
Yes. All calculations run directly in your browser using client-side JavaScript. Once the page loads, you can perform calculations without an internet connection.
What modes does the scientific calculator support?
The calculator supports DEG (degrees) and RAD (radians) modes for trigonometric functions. It also includes memory functions (M+, M-, MR, MC), parentheses for complex expressions, and a calculation history.
Is my calculation data stored or sent to a server?
No. All calculations happen locally in your browser. Nothing is sent to any server or stored remotely. Your calculation history exists only in your current browser session and is cleared when you close the tab.
What functions are available in this scientific calculator?
The calculator supports sin, cos, tan and their inverses, log (base 10), ln (natural log), square root, cube root, powers (x^y), factorial (n!), absolute value, constants (pi and e), and modulo operations. Full keyboard input is also supported.
