.
b) Then, the angle between the line and the pole will be:
where is the angle between the tangent to the catenary and the x-axis.
Explanation:
The catenary has the following general form:
a) The slope at any point will be given by the derivative of y.
At x=14:
.
b) The angle between the tangent to the catenary and the x-axis at a given point will be given by:
⇒
Then, the angle between the line and the pole will be:
