Question

Which of the following sets of parametric equations is equivalent to  ?

Quizplus · Accepted Answer

The only difference between the given parametric equations and the answer choices is in one of the digits in the second parameter (specifically, the third digit from the end). Changing this digit changes the value of the parameter, which affects the path traced by the curve. Option A differs in the third digit from the end, which means it represents a different curve than the given parametric equations, but the other options differ in more significant digits and therefore represent drastically different curves.
