Can you help me solve this please?
Thank you.
A ladder that is 6m long rests with one end on the horizontal ground, and the other end against a vertical wall. Considering the ground and the wall as the X- and Y-axes respectively, find the locus of the mindpoint of the ladder.
1. Draw the ladder in several different positions and determine the midpoint of the ladder.
2. Connect the midpoints by a smooth curve.
3. Let F denote the footpoint of the ladder with F(t, 0) and T the top of the ladder with . Then the midpoint of the ladder is
Keep in mind that
4. That means the curve of all midpoints is described by the parametric equation:
5. Solve the first equation for t and plug in this term into the 2nd equation. Re-arrange the equation until you have the standard equation of a circle around the origin with radius 3.
