Hello,
Consider the matrix A=[2/3 -2/3; 2/3 7/3].
Consider 10000 equally spaced points on the unit circle in R2 (assume Euclidian
distance). The coordinates of each of these points define a column vector
v in R2. Compute w = Av for all points, interprete the resulting vectors
again as points in the plane, and draw all resulting points in one figure.
What i need to do?

Unless you show some sample code where you have tried something, it's best to ask your professor or the TA for help to get started.

My hint would be this:
1.) Think about what equation every point on the unit circle satisfies in terms of cos(theta) and sin(theta).
2.) Generate 10,000 equally-spaced angles between [0,2*pi]
I think any more help than that and I'm just writing the code for your assignment.

oh sorry, Matt is correct!! I'm trying to do too many things at once. You should follow Matt's suggestion then and generate an equally spaced vector from 0 to 2*pi. I'll edit my post, but leave comment to show that Matt correctly pointed out my mistake.
