Scientific Calculator
A complete online scientific calculator with a physical-style button grid: type by pressing keys instead of typing. Trigonometry with degree/radian switching, inverse trig, natural and base-10 logarithms, square/cube/nth roots, powers, e^x, 10^x, constants π and e, memory keys (M+, M−, MR, MC), Ans, RND, EXP notation and percent — every press appends to the display buffer and evaluates exactly, with clear guidance if an input is out of domain. Below, a single-operation reference evaluator shows step-by-step working for any one function.

Function reference — single-operation evaluator with steps
sin(x) — x in degrees
0.5
x = 30 °
- Using x as degrees (30°)
- 0.5
- Using x as radians (30 rad)
- -0.988032
- Angle mode
- Degrees
- Operand x
- 30
Solution
- 1Convert degrees to radiansx = 30° × π/180 = 0.523599 rad
- 2Apply sinsin(0.523599) = 0.5

Formula
y = f(x), f ∈ {sin, cos, tan, sin⁻¹, cos⁻¹, tan⁻¹, ln, log₁₀, √, x^y, e^x}
- • Deg mode: trig inputs are converted with x·π/180
- • Rad mode: x is used as-is
- • Inverse trig returns an angle; both degree and radian values are shown
Pro tips
- • Use the interactive keypad above — every key appends to the display buffer and shows a live result before you press =.
- • Deg vs Rad matters: sin(30) is 0.5 in degrees but -0.988 in radians — the segmented toggle controls both the keypad and this reference evaluator.
- • ⁿ√x inserts ^(1/ — type the root n, then close the parenthesis (e.g. ^(1/4) for the fourth root).
- • M+/M− store the displayed value, MR recalls it, and Ans re-uses your last result inside the next expression.
