Expression Evaluator and Calculator
Instructions
- Enter the mathematical expression to evaluate.
Inputs
Make sure to specify function arguments within parentheses.
✅ sin(x)
❌ sin x
Make sure all multiplication is explicit. Implicit multiplication can yield incorrect guesses of intent.
✅ 5*x*cos(x)
❌ 5x cos(x)
Use e for a compact scientific notation.
5e3 = 5000
1.5e1 = 15
log(x) refers to the natural log of x. Use log(x)/log(n) to represent another base, n, for example log(x)/log(10) for the decimal base.
log(100)/log(10) = 2
log(e^2) = 2
| + | Addition. Example: 1 + 2 = 4 |
