* Objectives
At the end of this tutorial, you will be able to,
- Create simple plots of mathematical functions.
- Use the Figure window to study plots better.
* Error if Ipython not installed
** `ERROR: matplotlib could NOT be imported! Starting normal IPython.`
* Plot UI

* Exercise 1
Plot (sin(x)*sin(x))/x.
1. Save the plot by the sinsquarebyx.pdf in pdf format.
2. Zoom and find the maxima.
3. Bring it back to initial position.
* Summary
In this tutorial,we have learnt to-
- Start Ipython with pylab.
- Use the linspace function to create `num` equally spaced points in a region.
- Find the length of sequnces using len function.
- Plot mathematical functions using plot.
- Clear drawing area using clf.
- Plott mathematical functions using plot.
- Use the UI of plot
- Save
- Zoom
- Move axis
- Back and Forward Button
- Home
* Evaluation
1. Create 100 equally spaced points between -pi/2 and pi/2?
2. What will the command ''linspace(-pi,pi,100)'' do.
- returns 100 evenly spaced samples from -pi to pi
- returns 100 evenly spaced samples from -pi to pi excluding pi but including -pi
- returns 100 evenly spaced samples from -pi to pi excluding -pi but including pi
- returns 100 evenly spaced samples from -pi to pi including both -pi and pi
3. How do find the length of a sequence.
* Solutions...
1. linspace(-pi/2,pi/2,100)
2.
returns 100 evenly spaced samples from -pi to pi including both -pi and pi
3. len(sequence\_name)
