a.
To find: Number of degrees axis must be rotated to eliminate the
a.
Answer to Problem 8CT
Explanation of Solution
Given information:
If any conic in the form
Then angle must be rotated to remove
Given
On comparing with standard equation
We get
On substituting values
We get
Therefore
Number of degrees axis must be rotated to eliminate
b.
To find:Graph the conic and use a graphing utility to confirm result.
b.
Explanation of Solution
Given information:
Solve
Therefore
Substitute these values in the given equation
We get
The graph will be Parabola
Red colour lines represent the Hyperbola of equation-(1)
Green colour lines represent the Hyperbola of equation-(2)
So, by graphing Utility it was verified.
