It is easy to draw all the types of arcs in plots. Hence a multiple plot may help under such situations. I attempted to draw for a few problems, but found it difficult. Can any one help in drawing the same to get neat and clean output drawings for me to explain the answer to students.
Maple drawing shows all outer portions of circles.I used snipping tool to get cropped picture for first problem.
I already got a similar problem and got a response that i should use being forward and backward, but that seems to be not worth it many a times since figures become bigger in maple drawing with outer rectangles used for eliminating portions. (Ex: problem 1, not shown here)
