Calc-X: Your Scientific Calculator

A powerful tool for all your mathematical needs

Overview

Welcome to Calc-X, a versatile scientific calculator designed to handle everything from basic arithmetic to advanced trigonometric and logarithmic functions. Whether you're a student, engineer, or math enthusiast, Calc-X has you covered.

Usage Guidelines

Input: Click the buttons or type your expression directly from keyboard.
Clear: Use "AC" to reset the calculator.
Backspace: "⌫" removes the last character or function (e.g., "sin(").
Mode: Toggle between "DEG" (degrees) and "RAD" (radians) for trigonometric functions.
Evaluate: Press "=" to compute the result.
History: Access past calculations via the history button.

Frequently Asked Questions

How do I use implicit multiplication?

Simply write terms next to each other, e.g., "2sin(30)" is interpreted as "2 * sin(30)".

What happens if I enter an invalid expression?

Calc-X will display an error message, such as "Division by zero" or "Mismatched parentheses".

Can I reuse past calculations?

Yes! Click the history button to view and select previous expressions.
