How to Use the Scientific Calculator?

Our completely free Scientific Calculator gives you all the essential functions for advanced mathematics, physics, and engineering homework. Here is a quick guide to some of the advanced features:

Trigonometry: Use the sin, cos, and tan buttons. Make sure to toggle between DEG (Degrees) and RAD (Radians) depending on what your formula requires!
Exponents & Roots: Use the xʸ button to raise a number to any power (e.g., 2^3 = 8). Use the √ button to find the square root of a number.
Constants: Quickly insert Mathematical constants like π (Pi) or e (Euler's number) directly into your equations.
Previous Answer: Click the Ans button to insert the result of your very last calculation into your current equation.

Frequently Asked Questions (FAQ)

What is the difference between DEG and RAD?

DEG stands for Degrees (where a full circle is 360°), and RAD stands for Radians (where a full circle is 2π). When solving trigonometry problems (sine, cosine, tangent), it is vital to have the calculator set to the correct mode for your specific math problem.

Is my calculation history saved online?

No, your privacy is fully protected. Our Scientific Calculator is built using client-side JavaScript, meaning all the complex math processing happens directly on your device's CPU. Nothing is ever sent to a server, and the tool works perfectly even without an internet connection.
