draw a spiral as of a 3D plot where x and y are dependent on z, which is the rotation angle varying from 0 to 10pi. The x and y values are mapped as sin(theta) and cos(theta). The spiral effect is accomplished by plotting theta on the z axis. Use the step increase of theta to be .1 Turn the grid on. Show the matlab code and resulting figure.
