1. Write the following equation in standard form, find the center, vertices, and foci, asymptotes (if needed) and graph the equation. 4x2 - 25y2 + 16x +50y + 91 = 02. Eliminate the parameter and obtain the standard form of the rectangular equation and state what type of function this is: x = 4 +3 sec 0, y = -1 + 2 tan 03.Find a set of parametric equations for the rectangular equation: y = 4 x2 , where t = -1 at the point (1,3)
