How to Use
- Click numbers or use keyboard (0-9) to enter values
- Click operations or use keyboard (+, ?, ?, ?) to perform calculations
- Use scientific functions (sin, cos, tan, log, ln, ?, etc.) for advanced calculations
- Toggle between DEG (degrees) and RAD (radians) for trigonometric functions
- Click = or press Enter to get the result
- Click Clear or press Escape/C to reset the calculator
- Click ? or press Backspace to delete the last digit
Compute advanced expressions with powers, roots, trigonometric functions, and logarithms for school, engineering, and technical work.
Formula
Core functions: sin(x), cos(x), tan(x), log(x), ln(x), x^y, sqrt(x), factorial n!.
Worked Example
expressionsin(30°) + log10(1000) + 2^4
Result: 19.5Combining trigonometric and logarithmic terms with exponentiation yields a compact result from a mixed scientific expression.
Frequently Asked Questions
Should trigonometric input be in degrees or radians?
That depends on mode setting. Confirm mode before calculating, especially for exam or engineering contexts.
Is this useful for calculus checks?
Yes. It is useful for evaluating expressions and sanity-checking intermediate values during calculus and physics work.
