You'll have to create data arrays containing theta and V values. To get you started,

theta = [0 20 45]; 
V = [12.7 15 6.4]; 
plot(theta,V)

Sure enough.

You see what you have done here is not actually answer the question at all. True you graph a part of the function but you don't give an answer. I am here looking for help with MATLAB, not a fight.
