Discover the Power of Our Online Scientific Calculator
Our online Scientific Calculator is a versatile and user-friendly tool designed to handle a wide range of mathematical computations. Whether you're a student tackling complex homework problems, an engineer performing technical calculations, or a scientist in need of quick and accurate results, this calculator is built to meet your needs. It combines the simplicity of a basic calculator with the advanced functions required for scientific and engineering tasks.
Key Features of the Scientific Calculator:
- Standard Arithmetic Operations: Includes addition, subtraction, multiplication, division, and percentage calculations.
- Trigonometric Functions: Calculate sine (sin), cosine (cos), and tangent (tan) for angles in degrees or radians. Inverse trigonometric functions (sin-1, cos-1, tan-1) are also available.
- DEG/RAD Mode: Easily switch between degrees and radians for trigonometric calculations.
- Logarithmic Functions: Supports both base-10 logarithms (log) and natural logarithms (ln).
- Exponential and Power Functions: Easily calculate powers (xy) and use the constant 'e'.
- Roots and Factorials: Compute square roots (√) and factorials (x!).
- Constants: Quick access to mathematical constants like Pi (Ï€) and Euler's number (e).
- Parentheses: Use parentheses to define the order of operations for complex expressions.
- Memory Functions: Store (MS), recall (MR), clear (MC), add to (M+), and subtract from (M-) memory for multi-step calculations.
- Ans Function: Quickly recall the last calculated answer.
- Sign Toggle (+/-) and Reciprocal (1/x): Easily change the sign of a number or find its reciprocal.
- History Display: Keep track of your previous calculation or current operation.
- Responsive Design: Works seamlessly on desktops, tablets, and mobile devices.

Frequently Asked Questions (Scientific Calculator)
How accurate is the scientific calculator?
Our scientific calculator uses JavaScript's Math library and the Math.js library for more complex operations, which are designed for high precision in floating-point arithmetic. For most academic and professional purposes, the accuracy is more than sufficient. However, like all digital calculators, extremely complex calculations involving very large or very small numbers might be subject to inherent floating-point limitations.
Does the calculator support calculations with degrees or radians for trigonometric functions?
Yes! This calculator includes a DEG/RAD button that allows you to switch between degrees and radians for the input and output of trigonometric functions (sin, cos, tan, sin-1, cos-1, tan-1). The current mode is displayed on the button.
How do I use the memory functions (MS, MR, MC, M+, M-)?
The memory functions allow you to store and retrieve numbers:
- MS (Memory Store): Saves the currently displayed number into memory. Any previous number in memory is overwritten.
- MR (Memory Recall): Retrieves the number stored in memory and displays it.
- MC (Memory Clear): Clears the memory, setting its value to 0.
- M+ (Memory Add): Adds the currently displayed number to the value in memory.
- M- (Memory Subtract): Subtracts the currently displayed number from the value in memory.
How do I use the +/- (sign toggle) and 1/x (reciprocal) buttons?
- +/- (Sign Toggle): Press this button to change the sign of the number currently on the display. For example, if '5' is displayed, pressing '+/-' will change it to '-5', and vice-versa.
- 1/x (Reciprocal): Press this button to calculate the reciprocal (1 divided by the number) of the value currently on the display. For example, if '4' is displayed, pressing '1/x' will display '0.25'. It will show an error if you try to find the reciprocal of zero.
Can I use keyboard inputs with the scientific calculator?
Yes! The scientific calculator supports keyboard inputs for convenience. You can use: number keys (0-9), operators (+, -, *, /), decimal point (.), equals (Enter or =), clear (Escape), backspace, parentheses ((, )), and percentage (%). For specific scientific functions, you will need to click the on-screen buttons.
What does 'Error' mean on the display?
An 'Error' message typically appears if you attempt an invalid mathematical operation. Common causes include: division by zero, taking the logarithm of a non-positive number, taking the square root of a negative number, or incorrect syntax. Press 'AC' to reset.
