Proof of the cut plane and cylindrical with using alternative algebra and vectors, but proof of cut slope. When and how to use alternatives to linear algebra and matrix.
Proving cutouts on the plane and the cylinder using the vector algebra and essentially cuts the plane, but to prove when and how to use the linear algebra and matrix.
The proof of a plane cuts, when, and with the cylindrical algebraic method and vector as the main proof of a plane but cuts. The methods of linear algebra and matrix.
