Semi elliptical Arch Bridge An arch in the shape of the upper half of an ellipse is used to support a bridge that is to span a river meters wide. The center of the arch is meters above the center of the river. See the figure. Write an equation for the ellipse in which the x-axis coincides with the water level and the y-axis passes through the center of the arch.
Find the equation of the parabola described. Find the two points that define the latus rectum, and graph the equation by hand.
Vertex at , axis of symmetry is the x-axis; containing the point.
In Problems 31– 42, rotate the axes so that the new equation contains no xy-term. Analyze and graph the new equation. Refer to Problems 21–30 for Problems 31– 40.
