Your inputs

How it works

  1. 1

    Enter the angle value in radians.

  2. 2

    The calculator computes e^x and e^(-x).

  3. 3

    Subtract e^(-x) from e^x.

  4. 4

    Divide the result by 2 to get sinh(x).

(exp(angle) - exp(-angle)) / 2

Frequently asked questions

What is hyperbolic sine?

Hyperbolic sine, sinh(x), is defined as (e^x - e^(-x))/2. It is analogous to the sine function but for hyperbolas.

Can I input degrees?

This calculator expects radians. To convert degrees to radians, multiply by π/180.

What is the range of sinh(x)?

The output can be any real number. For large positive x, sinh(x) grows exponentially; for large negative x, it becomes very negative.

Formulas

The math behind this calculator, written out so you can verify the result.

Definition

sinh(x) = (e^x - e^(-x)) / 2

This is the standard definition using exponential functions.

Example:

Input: x = 1

Calculation: (e^1 - e^(-1)) / 2

Result: ≈ 1.1752

Real-world use cases

Where this calculation shows up in everyday life.

Physics

Describes the shape of a hanging cable (catenary) and relativistic velocity addition.

Example: Catenary curve y = a·cosh(x/a)

Engineering

Used in transmission line theory and heat transfer calculations.

Example: Voltage distribution along a transmission line

Mathematics

Appears in integrals, series expansions, and solutions to differential equations.

Example: Solving y'' - y = 0

Tips and common mistakes

Tips

  • Use radians for most mathematical contexts.
  • For large angles, the result grows very quickly; consider using scientific notation.
  • Remember that sinh(x) is an odd function: sinh(-x) = -sinh(x).

Common Mistakes to Avoid

  • Confusing sinh(x) with sin(x).
  • Forgetting to convert degrees to radians.
  • Using degrees when the formula expects radians.

Assumptions and limitations

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
