Code Explanation is as follows

1) I started with input variables like length l1 & l2

2) Then I gave values for Thata1 & Theta2

3) After that I mentioned ct value

4) Then as per Skill-Lync tutorial video I formed equation for x1,y1,x2,y2

5) Then I did Plotting of all the coordinates

6) Then I used pause command to make it look good and realistic

7) Later I used Movie M command to combine all figures in an animation

8) At the end saved it in .avi format

Error faced & steps taken to overcome it are as follows

Actually errors I got was because of my silly typing mistakes where at some point I mentioned y0 as yO i.e. instead of writing numerical zero I bymistake wrote alphabet 'O' which I later noticed & rectified it.

Another error i faced was because of not mentioning coma & semi-colon that too I rectified it and my problem solved

Screenshots of errors faced are as follows
