Plot a circle of unit radius. To do this, first generate thedata (x and y coordinates of 100 points on the circle), then plotthe data. For generating data, use the parametric equation of aunit circle: x = cos θ y = sin θ 0 <= θ <= 2π The plot mustcontain a title and labels for the x and y axis. NOTE: If yourcircle looks more like an ellipse, it is because of MATLAB’sdefault rectangular axes. To change this, use the axis command.Type help axis to see what you need to do to change the axes squareor equal.
