MOHO animation for math derivative

I'm looking for a MOHO user who builds a MOHO animation like that of [login to view URL] but based on my image [login to view URL] in this way: 1) The blue straight line rotates around point P until it becomes tangent to the red curve in P. 2) The blue spot in Q moves accordingly as in Sample.mp4. 3) The dotted line Q-R (down to the X axis) moves accordingly until it overlaps the dottet line P-X, and at this stage the characters Q and R disappear. 4) While the blue straight line rotates, the arc indicating the Beta angle grows accordingly and the letter Beta moves accordingly. 5) The animation has to include all the cahracters and the colors of Sample.png.
