Given information
Figure 1 shows the given diagram.
Step-by-step explanation
Step 1.
The parametric equation for a circle of radius 
is as follows:
is as follows:
Consider that 
increases to the point $R$ and construct the line segment from the 
parallel to the 
axis and the line segment from the 
parallel to the 
axis.
increases to the point $R$ and construct the line segment from the parallel to the axis and the line segment from the parallel to the axis.Because both lines cross at point 
, they are considered intersecting lines. Then, based on the diagram,
, they are considered intersecting lines. Then, based on the diagram,
Then,
Then, the angle 
.
.Then,
From the above given diagram,
