Function
src/index.ts:853nerdamer.atan
nerdamer.atan(x: ExpressionInput): ExpressionComputes the arctangent (inverse tangent) of an expression.
Returns exact symbolic values involving π for well-known inputs:
0 → 0, 1/√3 → π/6, 1 → π/4, √3 → π/3.
Uses the identity atan(-x) = -atan(x) for negative arguments.
At infinity: atan(+∞) = π/2, atan(−∞) = −π/2.
Parameters
| Name | Type | Description |
|---|---|---|
x | ExpressionInput | The input expression. |
Returns
Expression — The arctangent of x in radians.
Examples
atan(0).text() // "0"
atan(1).text() // "1/4*pi"
atan('sqrt(3)').text() // "1/3*pi"
// Symbolic
atan('x').text() // "atan(x)"
