Bring to Canonical Form
The teacher will be very surprised to see your correct solution 😉
What can a canonical calculator do?
- For a given equation it finds:
- Canonical form of the equation (for lines and surfaces of second order)
- Basis-vector of canonical coordinate system (for 2nd order lines)
- Center of canonical coordinate system (for 2nd order lines)
- Detailed Solution in Two Ways:
- Direct method with transition to a new center of coordinates and rotation around a new center of coordinates (for lines)
- Method of invariants with calculation of a set of determinants (for lines and surfaces)
- Plot a graph of the second order line, plot the center of the canonical system and the basis vectors of the canonical system
