(a)
To find:the whether the reflector in the telescope is elliptical, parabolic or hyperbolic.
(a)
Answer to Problem 46E
This conic is an ellipse.
Explanation of Solution
Given:
Concept used:
The general equation for
Where
As by changing the values of some of the constants, the shape of the corresponding conic also changes.
If
If
If
Calculation:
Consider the equation as:
Which models the shape of a reflecting mirror in a telescope.
To determine whether the reflector is elliptical, parabolic, or hyperbolic.
Write the above equation in the standard conic form:
Use the discriminant of the equation to identify the conic as:
Hence, this conic is an ellipse.
(b)
To sketch:the graph of the equation using the graphing calculator.
(b)
