Solution animation · expression tree
Type an expression above — its parse tree appears here and evaluates bottom-up in precedence order.
What operations are supported?
Arithmetic (+ − × ÷), modulo (%), power (^, right-associative), factorial (!), parentheses; functions sin/cos/tan and inverses, hyperbolic sinh/cosh/tanh, ln, log10, sqrt/cbrt, abs, exp; constants π and e. Trig supports a DEG/RAD toggle.
FAQ
Can I type with the keyboard?
Yes. Type numbers, operators and function names (e.g. sqrt(9), sin(30)) in the expression box and press Enter.
Degrees vs radians?
Degrees use 360° per turn (sin(90)=1); radians use 2π (sin(π/2)=1). Tap DEG/RAD to switch.
使用步骤How to use
- 直接键入表达式，如 sin(30) + sqrt(16) * 2^3Type an expression such as sin(30) + sqrt(16) * 2^3
- 按需要切换角度 DEG / 弧度 RADSwitch between DEG and RAD as needed
- 回车计算，从历史记录点回结果复用Press Enter and reuse earlier results from history
