# Scientific Calculator

Online scientific calculator with trigonometry, logarithms, exponents, and advanced math functions. Solve complex equations instantly in your browser.

**Use this tool:** [Scientific Calculator](https://findutils.com/calculate/scientific-calculator/)

## Programmatic access

- REST id `scientific-calculator`: POST https://api.findutils.com/api/tools/scientific-calculator/execute (reference: https://findutils.com/api/scientific-calculator/)
- MCP tool `scientific_calculator` on https://mcp.findutils.com (reference: https://findutils.com/mcp/scientific-calculator/)

## Why use our Scientific Calculator?

Our scientific calculator provides all the essential functions for students, engineers, and scientists. Perform trigonometric calculations, logarithms, exponentials, and more. Switch between radians and degrees mode, use memory functions, and calculate factorials - all in your browser without any downloads.

## Tips for Faster Calculations

- Switch to RAD mode before any calculus-related trigonometric computation to avoid conversion errors.
- Use the memory store (MS) button to save a partial result, then recall it with MR in a later step instead of writing it down.
- Parentheses let you control operator precedence; wrap sub-expressions to guarantee the correct evaluation order.
- The percentage key converts a number to its decimal form instantly, which speeds up discount and markup calculations.
- Chain calculations by using the previous result as the starting value for the next expression instead of clearing and re-entering.

## Frequently Asked Questions

### What functions are available?

Our calculator includes trigonometric functions (sin, cos, tan) with RAD and DEG modes, hyperbolic functions (sinh, cosh, tanh), logarithms (log, ln), square root, cube root, nth root, power functions, factorial, reciprocal, percentage, and memory keys (MC, MR, M+, M-, MS). Inverse trigonometric and inverse hyperbolic functions (asin, acos, atan, asinh, acosh, atanh) can be typed into an expression.

### What is the difference between RAD and DEG mode?

RAD (radians) and DEG (degrees) modes affect how trigonometric functions interpret angles. Use DEG for degree-based calculations (0-360) and RAD for radian-based calculations (0-2pi). Hyperbolic functions take a plain number rather than an angle, so they return the same result in either mode.

### How do memory functions work?

MC clears memory, MR recalls stored value, M+ adds current display to memory, M- subtracts from memory, and MS stores the current display in memory.

### Can I use keyboard shortcuts?

Currently, the calculator works with mouse/touch input. Keyboard support allows number input and basic operators.

### Is my calculation history saved?

No, calculations are performed locally in your browser and are not saved. Your privacy is protected.

### Does this scientific calculator require a signup?

No. FindUtils Scientific Calculator requires no signup and has no usage limits. It runs entirely in your browser so nothing is uploaded to any server.

### Can this replace a TI-84 or Casio scientific calculator?

For expression evaluation, trigonometry, logarithms, and exponents, yes. It does not support graphing or programmable scripts, so for advanced coursework requiring those features you still need a graphing calculator.

### How do I calculate a factorial?

Enter the number and press the factorial (n!) button. For example, enter 5 then press n! to get 120. Factorials are useful in probability and combinatorics.

### Does the calculator follow standard order of operations?

Yes. The calculator follows standard mathematical order of operations (PEMDAS/BODMAS). Use parentheses to override the default precedence when needed.

### Can I use this on my phone or tablet?

Absolutely. The calculator is fully responsive and works on any device with a modern browser, including smartphones and tablets. No app download is required.
