A curve is given parametrically by x = 1 + 7e tan a cos 0, y = 5 + 7e tan a sin 0. where a is a constant in the interval (0, /2) and is a real- valued parameter. In this example, we can consider the whole curve by allowing the intrinsic angle y to take any real value. Find an expression for tan y in terms of 0 and a. Now, find an expression for the arclength s in terms of 0 and a, choosing a sign convention such that s is positive and setting for convenience s 0 as 0-0. Finally, combine the previous two results to find a relation between s and y. From the form of this relation (and/or the original parametric equations) what shape must the curve have?
