Hyperboloid of one sheet 25 x 2 + 25 y 2 − z 2 = 25 and elliptic cone − 25 x 2 + 75 y 2 + z 2 = 0 are represented in the following figure along with their intersection curves. Identify the intersection curves and find their equations (Hint: Find y from the system consisting of the equations of the surfaces.)
