Question: In mathematics we can assume that `sin(t1)` is equal to `t1` for very small angles. How to do that in Matlab?

```
syms t1;
res = sin(t1);
res2= MAGIC(res,t1);

```

I need `MAGIC`to change `res`, such that it becomes `t1`.

Thanks

Answer: 
In first your problem is about the spelling of the input class, should be Input instead of input. And you have to import the class with the good namespace. 

```
use Illuminate\Support\Facades\Input;

```

If you want it called 'input' not 'Input', add this :

```
use Illuminate\Support\Facades\Input as input;

```

Second, It's a dirty way to store into the database via route.php,
and you're not processing data validation.
If a sent parameter isn't what you expected, maybe an SQL error will appear, its caused by the data type.
You should use controller to interact with information and store via the model in the controller method.

The route.php file handles routing.
It is designed to make the link between the controller and the asked route.

Regards.
Declaration in config/app.php under aliases:-

```
'Input' => Illuminate\Support\Facades\Input::class,

```

Or You can import Input facade directly as required,

```
use Illuminate\Support\Facades\Input;

```

or

```
use Illuminate\Support\Facades\Input as input;

```
