To evaluate this expression, you need to know the definitions of the hyperbolic trigonometric functions:

- `sinh(x)` is the hyperbolic sine function, defined as: `sinh(x) = (e^x - e^-x) / 2`
- `cosh(x)` is the hyperbolic cosine function, defined as: `cosh(x) = (e^x + e^-x) / 2`
- `tanh(x)` is the hyperbolic tangent function, defined as: `tanh(x) = sinh(x) / cosh(x)`
- `sech(x)` is the hyperbolic secant function, defined as: `sech(x) = 1 / cosh(x)`

Substituting these definitions into the given expression, we get:

```
sinh(1) + cosh(1) + tanh(1) - sech(1)
= (e^1 - e^-1) / 2 + (e^1 + e^-1) / 2 + (e^1 - e^-1) / (e^1 + e^-1) - 1 / (e^1 + e^-1)
```

Simplifying this expression, we get:

```
(e^2 - 1) / (2e^1) + (e^2 - 1) / (2e^1) - 1 / (2e^1)
= (e^2 - 1) / (2e^1) - 1 / (2e^1)
= (e^2 - 2) / (2e^1)
```

So, the final result is:

```
sinh(1) + cosh(1) + tanh(1) - sech(1) = (e^2 - 2) / (2e^1)
```
sinh(1) + cosh(1) + tanh(1) - sech(1)=

I believe you made a typo in your expression. Let's assume you meant to ask for the value of the expression sinh(1) + cosh(1) + tanh(1) - sech(1). To find the value of this expression, we first need to evaluate each of these hyperbolic functions at 1.

sinh(1) = 1
cosh(1) = 2
tanh(1) = 1
sech(1) = 1

Now, let's add these values:

sinh(1) + cosh(1) + tanh(1) - sech(1) = 1 + 2 + 1 - 1 = 1

Therefore, the value of the expression is 1.
