Recieving error that states "Vectors must be the same length".

I am trying to plot Y in terms of X. I was able to plot the first graph as incremented by values of pi/2. However, I have not changed the bounds of x, just changed the value of the intermediate steps. ie; from x= -pi:pi/2:pi; to x=-pi:pi/3:pi; When doing so, I receive the error that says vectors must be of the same length. Why is this?

By changing the increment you have changed the length of X (from 5 to 7 in your case). If Y matches X (with 5 elements), it does not match X with 7 elements. So you have to compute Y for your new X with 7 values, to avoid the error.

Thanks, I couldn't figure out why the vector change when I was only changing the increments and not the bounds.
