Draw a spiral as of a 3-D plot where x and y are dependent on z, which is the rotation angle varying from 0 to 10*pi (i.e., five complete revolutions). The x and y values are mapped as sin( ) θ and cos( ) θ , the classic means of describing a circle. The spiral effect is accomplished by plotting θ on the z-axis. Use the step increase of θ to be 0.1. Turn the grid on. Show the Matlab code and the resulting figure.
