Tanh On Calculator
🔍 What is Tanh?
The hyperbolic tangent function, denoted as tanh(x), is a mathematical function used widely in calculus, physics, engineering, machine learning, and neural networks.
The formula for tanh(x) is: tanh(x)=sinh(x)cosh(x)=ex−e−xex+e−x\tanh(x) = \frac{\sinh(x)}{\cosh(x)} = \frac{e^x – e^{-x}}{e^x + e^{-x}}tanh(x)=cosh(x)sinh(x)=ex+e−xex−e−x
The value of tanh(x) always lies between -1 and 1. It is an odd function, meaning tanh(-x) = -tanh(x)
, and is similar in shape to the regular tangent function but without undefined points.

5. What happens if I enter an invalid input?
The calculator will show an alert prompting you to enter a valid number.
6. What is tanh(0)?tanh(0)
is 0
.
7. Why is tanh used in neural networks?
It helps normalize data, making training more stable and efficient.
8. Is there a limit to how large the input can be?
Practically no, but extremely large inputs may round to -1 or 1 due to the function’s asymptotic nature.
9. What is the tanh of infinity?
As x → ∞, tanh(x)
→ 1; as x → -∞, tanh(x)
→ -1.
10. Does the calculator round the answer?
Yes, it rounds the result to six decimal places.
