(choose chapter or problem)

(a) Find and identify the traces of the quadric surface \(x^{2}+y^{2}-z^{2}=1\) and explain why the graph looks like the graph of the hyperboloid of one sheet in Table \(1\).

(b) If we change the equation in part (a) to \(x^{2}-y^{2}+z^{2}=1\), how is the graph affected?

(c) What if we change the equation in part (a) to \(x^{2}+y^{2}+2 y-z^{2}=0\)

x^2-y^2+z^2=1

x^2+y^2+2y-z^2=0
