A powerful online scientific calculator with functions for trigonometry (sin, cos, tan), logarithms (log), exponents, and more. Perfect for students and professionals. 

When "2 + 2" Isn't Enough: Unleash the Power of a Scientific Calculator.

For everyday math, a basic calculator is all you need. But when you step into the world of algebra, geometry, trigonometry, or science, you quickly run into problems that require more firepower. You need to find the sine of an angle, the logarithm of a number, or calculate with exponents.

That’s when you need a scientific calculator. It's the essential tool for any high school or college student, engineer, scientist, or anyone working with advanced mathematics. And you don't need to buy a physical one; a powerful version is always available right in your browser.

What Do All Those Extra Buttons Do?

A scientific calculator expands on a basic calculator with functions for more complex problems:

• Trigonometry: sin, cos, and tan for working with angles and triangles.

• Logarithms: log (base-10) and ln (natural log) for solving exponential equations.

• Exponents and Roots: x², xʸ, and √ for handling powers and roots.

• Scientific Notation: Easily work with very large or very small numbers.

• Constants: Quick access to important constants like Pi (π) and Euler's number (e).

Your Advanced Math Tool, Available Anywhere

Accessing these powerful functions is easy:

1. Open the Scientific Calculator: Go to the FreeXTool Scientific Calculator.

2. Perform Your Calculation: Use your mouse or keyboard to enter your equation using the standard and advanced functions.

3. Get Your Precise Answer: The calculator provides a high-precision answer for all your complex mathematical needs.

Crucial Pro-Tip: Degrees vs. Radians

This is the most common mistake students make! Before you do any trigonometry (sin, cos, tan), make sure your calculator is in the correct mode. If your problem uses angles in degrees (e.g., 90°), your calculator must be in "DEG" mode. If it uses radians (e.g., π/2), it must be in "RAD" mode. The wrong mode will give you a completely different and incorrect answer.
