Using Octave or MATLAB(preferably Octave):

A robotic arm is able to move in two dimensions (x & y). Starting at the home position, the robotic arm's movement is defined by

x velocity= sin(2*(y-3))+a*cos(y*x)

y velocity= cos(2*(x-2))-b*sin(-3*x*y)

a= 0.7

b= 0.5

Plot the x and y positions of the arm in the top subplot for 8.5 seconds. Plot the velocities in the bottom plot.
