### Linearly independency for exponential functions

This is a supplementary notes for MATH211 ODE and Linear Algebra.

### Display the part of the graph beyond the axis limit in Matlab

When I tried to manually adjust the axis limits of a graph, Matlab will automatically cut off the part of the graph that is beyond the axis limits. This didn't happen before (and before means 2014a or earlier versions). I took a little while to find the cure. Just try the following scripts.

```
ax = gca;
ax.Clipping = 'off';
```

### Change default mail app in OS X

Here is the steps to change default mail app in OS X:

- Open
**Mail**app. - Select Preferences -> General. Under "Default email reader", select your preferred mail app.

I am running into a problem by following the steps: the default email reader changes back to the original mail app seconds after I made the change. Here is the solution that works for me. Open terminal. Copy and paste the following script.

`/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -all local,system,user`

Then try step 1-2 again, and it won't change back again!

### Finite time blow up in the hyperbolic Boussinesq system

- This is a joint work with
*Alexander Kiselev*. - The preprint is available on arXiv:1609.02468.
