2. Cubic equation - Wikipedia

   en.wikipedia.org/wiki/Cubic_equation

   Lagrange's method can be applied directly to the general cubic equation ax 3 + bx 2 + cx + d = 0, but the computation is simpler with the depressed cubic equation, t 3 + pt + q = 0. Lagrange's main idea was to work with the discrete Fourier transform of the roots instead of with the roots themselves.

3. Cubic plane curve - Wikipedia

   en.wikipedia.org/wiki/Cubic_plane_curve

   In mathematics, a cubic plane curve is a plane algebraic curve C defined by a cubic equation ⁠ F ( x , y , z ) = 0 {\displaystyle F(x,y,z)=0} ⁠ applied to homogeneous coordinates ⁠ ( x : y : z ) {\displaystyle (x:y:z)} ⁠ for the projective plane ; or the inhomogeneous version for the affine space determined by setting z = 1 in such an ...

4. Cubic surface - Wikipedia

   en.wikipedia.org/wiki/Cubic_surface

   In mathematics, a cubic surface is a surface in 3-dimensional space defined by one polynomial equation of degree 3. Cubic surfaces are fundamental examples in algebraic geometry . The theory is simplified by working in projective space rather than affine space , and so cubic surfaces are generally considered in projective 3-space P 3 ...

5. Resolvent cubic - Wikipedia

   en.wikipedia.org/wiki/Resolvent_cubic

   Graph of the polynomial function x 4 + x 3 – x 2 – 7x/4 – 1/2 (in green) together with the graph of its resolvent cubic R 4 (y) (in red). The roots of both polynomials are visible too. In algebra, a resolvent cubic is one of several distinct, although related, cubic polynomials defined from a monic polynomial of degree four:

6. Cubic function - Wikipedia

   en.wikipedia.org/wiki/Cubic_function

   The roots, stationary points, inflection point and concavity of a cubic polynomial x 3 − 6x 2 + 9x − 4 (solid black curve) and its first (dashed red) and second (dotted orange) derivatives. The critical points of a cubic function are its stationary points , that is the points where the slope of the function is zero. [ 2 ]

7. Cubic - Wikipedia

   en.wikipedia.org/wiki/Cubic

   Cubic crystal system, a crystal system where the unit cell is in the shape of a cube; Cubic function, a polynomial function of degree three; Cubic equation, a polynomial equation (reducible to ax 3 + bx 2 + cx + d = 0) Cubic form, a homogeneous polynomial of degree 3; Cubic graph (mathematics - graph theory), a graph where all vertices have ...
