    1. The problem statement, all variables and given/known data
    I have to make a plot with sin(t) (y values) vs cos(t) (x values). The values of t should be between -pi and pi. I'm supposed to use linspace.

    2. Relevant equations

    3. The attempt at a solution
    i used these lines:


    when i tried it out, the plot came out like this:

    If t is a real number, both sin t and cos t have values in the [-1, +1] interval, so your graph is correct (a circle).
