Part (a)
As shown in figure 1, c is inducing a counterclockwise orientation, so using trigonometry the equations are given by:
As:
if then and that is the condition for the problem.
Part (b)
As shown in figure 2, c is inducing a clockwise orientation, so using trigonometry the equations are given by:
As:
if then and that is the condition for the problem.
Part (c)
As shown in figure 3, c is now centered at the point (4, 3). Let's assume that it is inducing a counterclockwise orientation, so using trigonometry and doing a displacement of 4 in x-axis and 3 in y-axis, the equations are given by:
Where:
