Given:
Quadric surfaces and conic sections.
Each conic section has two axes and the quadratic equation in two variables of conic section
is generally represented as,
\(ax_1^2 + 2bx_1x_2 + cx_2^2 + dx^1 ex_2 + f = 0\)
Here, x_1 and x_2 can be considered as two coordinate axes.
Now, if the same quadratic equation is written in three variables, it will be as follows:
\(ax_1^2 + bx_2^2 + cx_3^2 + 2dx_1 x^2 + 2ex_1 x_3 + 2f_(x2x3) + gx_1 hx_2 ix_3 + j =0\)
The graph of this equation will be a quadric surface where x1, x and xy are three coordinate
axes.
Hence, quadric surfacesare the three-dimensional analogs of conic sections.

What are the standard equations for lines and conic sections in polar coordinates? Give examples.

The circle, ellipse, hyperbola, and parabola are examples of conic sections. Their
quation contains \(x^2 terms, y^2\) terms, or both.
When these terms both appear, are on the same side, and have different coefficients
with same signs, the equation is that of an ellipse.

Whether the statement “I noticed that depending on the values for
Aand B assuming that they are not both zero, the graph of
\(Ax^2 + By^2 = C\) can represent any of the conic sections other than a
parabola” “makes sense” or “does not make sense”, And explain
your reasoning.
