SINH

All functions > MATH > SINH

Returns the hyperbolic sine of a number.

Signatures

Returns: Hyperbolic sine result

SINH(number: T) → DOUBLE

Notes

• Definition: SINH(x) = (e^x - e^(-x)) / 2
• SINH(0) = 0
• Odd function: SINH(-x) = -SINH(x)
• Grows exponentially for large |x|
• Related to regular sine but for hyperbolic geometry
• Can be positive or negative depending on input sign
• Returns NULL if input is NULL

Examples

SELECT
    f1 := SINH(0e0),  -- Hyperbolic sine of 0 is 0
    f2 := SINH(1e0),  -- Hyperbolic sine of 1
    f3 := SINH(-1e0),  -- Odd function: SINH(-1) = -SINH(1)
    f4 := SINH(2e0)  -- Hyperbolic sine of 2
