Inverse functions are calculated using logarithmic formulas.

🛡 Handles Special & Invalid Inputs

The calculator automatically detects undefined or invalid values.

  • coth(0) → Undefined
  • arcosh(x) when x < 1 → Invalid
  • artanh(x) when |x| ≥ 1 → Invalid

⚙️ How the Calculator Works

1️⃣ Select a hyperbolic or inverse hyperbolic function from the dropdown menu.

2️⃣ Enter a numeric value in the input field.

3️⃣ The calculator applies the correct mathematical formula:

  • Uses exponential formulas for sinh, cosh, tanh, etc.
  • Uses logarithmic formulas for inverse functions.

4️⃣ If the input falls outside the valid domain, the calculator shows “invalid input” or “undefined”.

5️⃣ The result is displayed instantly in the format:

function(value) = result

📐 Hyperbolic Functions Formulas Explained

Hyperbolic functions are analogs of trigonometric functions but for a hyperbola rather than a circle. They are widely used in calculus, physics, engineering, and complex analysis. This calculator computes both the basic hyperbolic functions sinh(x), cosh(x), tanh(x), coth(x), sech(x), csch(x) and their inverse counterparts arsinh(x), arcosh(x), artanh(x), arcoth(x), arsech(x), arcsch(x).

Each function can be expressed using exponential formulas. These formulas allow precise numeric computation and help handle special cases for undefined or invalid inputs.

Basic Hyperbolic Functions

sinh(x) – Hyperbolic sine: sinh(x) = (eˣ − e⁻ˣ) ÷ 2

cosh(x) – Hyperbolic cosine: cosh(x) = (eˣ + e⁻ˣ) ÷ 2

tanh(x) – Hyperbolic tangent: tanh(x) = sinh(x) ÷ cosh(x)

coth(x) – Hyperbolic cotangent: coth(x) = cosh(x) ÷ sinh(x)

sech(x) – Hyperbolic secant: sech(x) = 1 ÷ cosh(x)

csch(x) – Hyperbolic cosecant: csch(x) = 1 ÷ sinh(x)

Inverse Hyperbolic Functions

arsinh(x): arsinh(x) = ln(x + √(x² + 1))

arcosh(x): arcosh(x) = ln(x + √(x² − 1)), x ≥ 1

artanh(x): artanh(x) = ½ ln((1 + x)/(1 − x)), |x| < 1

arcoth(x): arcoth(x) = ½ ln((x + 1)/(x − 1)), |x| > 1

arsech(x): arsech(x) = ln((1 + √(1 − x²))/x), 0 < x ≤ 1

arcsch(x): arcsch(x) = ln((1/x) + √(1 + 1/x²)), x ≠ 0

Using these formulas, the calculator evaluates inputs instantly. It checks for special cases such as division by zero or invalid domains, ensuring accurate results. For instance, coth(0) and csch(0) are undefined because they involve division by zero, while arcosh(x) is only valid for x ≥ 1.

These hyperbolic functions are essential in solving differential equations, modeling exponential growth, describing catenary curves, and in many physics and engineering problems. Mastering their formulas helps in both computational and theoretical understanding.

The inverse hyperbolic formulas also allow solving for x when given a function value. For example, if sinh(x) = 2, using arsinh formula:

x = arsinh(2) = ln(2 + √(2² + 1)) ≈ 1.4436

This systematic approach ensures clarity, accuracy, and quick calculations, making this calculator a powerful tool for students, engineers, and professionals dealing with hyperbolic functions.

📌 Example

If you select:

sinh(x)

And enter:

x = 1

The calculator computes:

sinh(1) ≈ 1.1752

Using the formula (e¹ − e⁻¹) / 2.

Frequently Asked Questions About the
Hyperbolic Functions Calculator

Clear answers about computing hyperbolic and inverse hyperbolic functions quickly and accurately.

What does this calculator compute?

It calculates the values of hyperbolic functions such as sinh(x), cosh(x), tanh(x), coth(x), sech(x), csch(x) and their inverse functions including arsinh(x), arcosh(x), artanh(x), arcoth(x), arsech(x), and arcsch(x).

How does the calculator compute sinh(x) and cosh(x)?

It uses the exponential definitions: sinh(x) = (eˣ − e⁻ˣ) / 2 and cosh(x) = (eˣ + e⁻ˣ) / 2. Other functions like tanh(x) are derived from these formulas.

How are inverse hyperbolic functions calculated?

Inverse hyperbolic functions are computed using logarithmic formulas. For example, arsinh(x) = ln(x + √(x² + 1)) and artanh(x) = ½ ln((1 + x) / (1 − x)).

Does the calculator check for invalid inputs?

Yes. It automatically detects values outside the valid mathematical domain. For example, arcosh(x) is only defined for x ≥ 1, and artanh(x) is only valid when −1 < x < 1. If an invalid value is entered, the calculator displays “invalid input” or “undefined.”

Do I need to press a calculate button?

No. The calculator works in real time. As soon as you enter a value or change the selected function, the result updates automatically.

What happens when I enter 0 for special functions?

Some functions are undefined at 0. For example, coth(0) and csch(0) are undefined because they involve division by zero. The calculator correctly displays “undefined” in such cases.

Is this calculator suitable for students?

Yes. It is ideal for algebra, calculus, and engineering students who need quick and accurate hyperbolic function calculations for homework, quizzes, and exam preparation.

Can I use this calculator on mobile devices?

Yes. The calculator is fully responsive and works smoothly on smartphones, tablets, laptops, and desktop computers.

Is this calculator free to use?

Yes. It is completely free to use with no sign-up or hidden fees required.

How do I reset the calculator?

You can click the “Clear” button to remove the current input or use the “Reload Calculator” button to reset the function selection and start fresh.
