Get answers to common questions about using our scientific calculator effectively.
Click on the trigonometric function buttons (sin, cos, tan) and then enter your angle value. The calculator assumes degrees by default. For radians, you can convert using the formula: radians = degrees × π/180. For example, to calculate sin(30°), click 'sin' then enter '30' and press equals.
The 'ln' function calculates the natural logarithm (base e ≈ 2.718), while 'log' calculates the common logarithm (base 10). Natural logarithms are used in calculus and exponential growth problems, while common logarithms are used in scientific notation and pH calculations. For example: ln(e) = 1, while log(10) = 1.
Use the 'x²' button for squares, 'xʸ' for any power, or 'eˣ' for exponential functions. For x², enter the number first, then click x². For xʸ, enter the base number, click xʸ, enter the exponent, then equals. For example: to calculate 2³, enter '2', click 'xʸ', enter '3', then press equals to get 8.
Yes! Use the '(' and ')' buttons to group operations and control the order of calculations. The calculator follows the standard order of operations (PEMDAS/BODMAS). For example: (2+3)×4 = 20, while 2+3×4 = 14. Parentheses help you create complex expressions like sin(30°+45°) or (ln(10)+log(100))/2.
The history panel on the right shows your recent calculations. Click on any previous calculation to reuse the result in a new expression. You can clear the entire history using the trash icon. The history is stored locally in your browser and will persist between sessions until you clear it or clear your browser data.
π (pi ≈ 3.14159) is used in calculations involving circles, such as area (πr²) and circumference (2πr). The constant e (≈ 2.71828) is Euler's number, used in exponential and logarithmic functions, compound interest calculations, and natural growth/decay problems. Both are essential mathematical constants in advanced calculations.
Yes! You can use your keyboard for most operations: numbers (0-9), basic operators (+, -, *, /), decimal point (.), parentheses, and Enter for equals. The Escape key clears the display, and Backspace removes the last entered character. This makes calculations faster and more convenient for frequent users.
Our scientific calculator provides high precision for most educational and professional applications. It uses JavaScript's built-in mathematical functions, which provide approximately 15-17 significant digits of precision. For extremely high-precision scientific research or critical applications, specialized software may be required, but our calculator is excellent for students, engineers, and most professional use cases.
Click the 'x!' button after entering a number to calculate its factorial. A factorial (n!) is the product of all positive integers from 1 to n. For example: 5! = 5×4×3×2×1 = 120. Factorials are used in probability, statistics, combinatorics, and permutation calculations. Note that factorials grow very quickly - 10! = 3,628,800!
