In Exercise, consider the following. Suppose that the value of x and y are determined by another value, or parameter t. That is, x = x(t) and y = y(t). Then x and y are called parametric equations. We can show that the derivative of y with respect to x for parametric equations is given by . Determine the derivative for each of the following and write your answer in terms of the independent variable t.
