Full-featured scientific calculator with trig, log, powers, and memory functions.
Click or tap the buttons to build a mathematical expression. Use the digit buttons for numbers, operator buttons for arithmetic, and function buttons for trigonometric, logarithmic, and power operations. The expression displays at the top and the result appears below. Press the equals button or Enter to evaluate. The backspace button removes the last character and C clears everything.
This calculator supports sine, cosine, and tangent functions which operate in radians. The log function computes the base-10 logarithm while ln gives the natural logarithm. The square root button inserts a square root operation. The power button lets you raise any number to any exponent. Pi and e insert their mathematical constants. Parentheses allow you to group operations and control the order of evaluation.
Use MS to store the current result in memory, MR to recall it, M+ to add the current result to memory, M- to subtract from memory, and MC to clear memory. Memory persists as long as the page is open. This calculator handles complex nested expressions with proper operator precedence. All calculations are performed locally in your browser using a safe expression parser with no data sent to any server.
