• Canonical form of a elliptical paraboloid
• Canonical form of a double hyperboloid
• Canonical form of a imaginary ellipsoid
• Canonical form of a degenerate ellipse
• Canonical form of a parabola

• How to use it?

• Canonical form:
• x^2-2y^2-6x-8y-3=0
• (x-3)^2/25+(y+2)^2/49=1
• -x^2-6x+y^2-4y-8=0\:
• 2+x^2-y=0
• Plot:
• (z*cos(pi/4)-x*sin(pi/4))^2=(z*sin(pi/4)+(x-2)*cos(pi/4))^2+(y-5)^2
• -x^3+3*x-2=y
• 0.63=0.49+0.41*(1-exp(-0.17*x/(exp(-(y/(2805-y))^0.45)-x)))
• (y-x)*x^4+8=0
• ln(x+y)

• Identical expressions

• u=ln(x+y)
• u equally ln(x plus y)
• u=lnx+y

• Similar expressions

• u=ln(x-y)
• sin(z/(x+y))-(1/2)*ln(x+y-x*z^2)=0
