So the task is to determine the specified arclength satisfying and an initial condition of your convenience.

By two uses of the chain rule, observe that this can be rewritten in the form:

Can you finish it from there?

The task is to find the arc length in terms of the angle of the tangent from whatever direction.

Right, so what's the issue? If you follow through the above post, you'll see that this is easily obtained by plugging in after finding .
5. Thanks, this is perfect.
