Hi PF!

Here's my equation

Making it real, it plots well, but I cannot identify the first zero of the real component of the equation. NSolve and Reduce fail, though it plots so clearly.

Thanks for your time!

Here's my equation

Code:

```
0.5 Sech[0.997091 Sqrt[
2.4674 + \[Xi]\[Xi]^2]] (-1. ((0. +
3.7011 I) + (0. + 1.5 I) \[Xi]\[Xi]^2) Cosh[
0.997091 Sqrt[2.4674 + \[Xi]\[Xi]^2]] -
1. \[Sqrt](((0. + 3.7011 I) + (0. + 1.5 I) \[Xi]\[Xi]^2)^2 Cosh[
0.997091 Sqrt[2.4674 + \[Xi]\[Xi]^2]]^2 +
4. (2.4674 + \[Xi]\[Xi]^2)^(3/2)
Cosh[0.997091 Sqrt[2.4674 + \[Xi]\[Xi]^2]] Sinh[
0.997091 Sqrt[2.4674 + \[Xi]\[Xi]^2]]))
```

Thanks for your time!
