How to Use This Scientific Calculator

This powerful calculator is designed to handle a wide range of mathematical tasks. Here's how to get the most out of it:

• Basic Operations: Use the number buttons and + - × / for simple arithmetic.
• Scientific Functions: Click function buttons like sin, log, √ and then enter the number or expression in parentheses (e.g., sin(30)).
• Exponents: Use x^y for powers (e.g., 2^8) or x² for squaring.
• Parentheses: Use ( ) to group operations and control the order of calculations (e.g., (2+3)*4).
• Constants: Click π or e to input these mathematical constants.
• Memory: Store a value with MS, recall it with MR, add to it with M+, subtract with M-, and clear with MC.
• Last Answer: Press Ans to use the result of the previous calculation in a new one.
• History: Click "Show Calculation History" to see and reuse past calculations.
• Keyboard: You can also use your computer keyboard for faster input. Number keys, operators, Enter (=), Escape (AC), and Backspace (DEL) all work.

List of Functions and Operations

Basic Arithmetic

• Addition (+), Subtraction (-), Multiplication (×), Division (/)
• Percentage (%)
• Decimal Point (.)

Trigonometric Functions

• Sine (sin), Cosine (cos), Tangent (tan)

• Calculation History

About Scientific Calculators

A scientific calculator is an indispensable tool for students, teachers, engineers, and anyone who needs to perform technical calculations. Unlike a basic calculator, it can handle complex mathematical functions commonly used in science, engineering, and mathematics.

Key features include trigonometric functions (sine, cosine, tangent), logarithmic functions (log, ln), exponential functions, and the ability to work with constants like pi (π) and Euler's number (e). These capabilities make them essential for subjects like algebra, geometry, trigonometry, calculus, physics, and chemistry.
