Calculus Early Transcendental Functions
In Exercise, (a) find two explicit functions by solving the equation for $y$ in terms of $x,$ (b) sketch the graph of the equation and label the parts given by the corresponding explicit functions, (c) differentiate the explicit functions, and (d) find $d y / d x$ implicitly and show that the result is equivalent to that of part (c).
$$x^{2}+y^{2}=64$$
