### Your Input

**Find $$$\frac{d}{dx} \left(\cosh{\left(x \right)}\right)$$$.**

### Solution

**The derivative of the hyperbolic cosine is $$$\frac{d}{dx} \left(\cosh{\left(x \right)}\right) = \sinh{\left(x \right)}$$$:**

Thus, $$$\frac{d}{dx} \left(\cosh{\left(x \right)}\right) = \sinh{\left(x \right)}$$$.

### Answer

**$$$\frac{d}{dx} \left(\cosh{\left(x \right)}\right) = \sinh{\left(x \right)}$$$A**
