## Tanh Calculation Formula

Here’s the magical formula for calculating tanh. Ready to be a wizard?

```
tanh(x) = (e^x - e^-x) / (e^x + e^-x)
```

Bam! You’re a math wizard now!

## Tanh Categories

Here are the different categories of tanh. It’s like a math fashion show!

Categories | Range | Interpretation |
---|---|---|

## FAQs

**What is tanh?**Tanh is the hyperbolic tangent function.**How to calculate tanh?**Use the formula: tanh(x) = (e^x – e^-x) / (e^x + e^-x)**Where is tanh used?**Tanh is used in mathematics, physics, and engineering.**What is the range of tanh?**The range of tanh is from -1 to 1.**Is tanh the same as tan?**No, tanh is the hyperbolic tangent while tan is the tangent.**Can tanh be used for complex numbers?**Yes, tanh can be used for complex numbers.**What is the derivative of tanh?**The derivative of tanh is 1 – (tanh^2).**Why is tanh used in neural networks?**Tanh is used in neural networks because it’s output range is normalized from -1 to 1.**What is the inverse of tanh?**The inverse of tanh is called the artanh or inverse hyperbolic tangent.**Is tanh a linear function?**No, tanh is not a linear function.
