• Canonical form:
• 2x^2-3y^2+z^2+4x+6y-4z-3=0
• 4y^2+2z^2-3x+16y-8z=0
• 4x^2-9y^2+32x-54y+73=0
• 2*x^2+2*y^2+2*z^2+2*x*y-2*x*z-2*y*z-14*x-14*y+4*z=26
• Plot:
• tg(x*y+0.4)-x^2
• 5/x+3-y=|y-2+3/x|
• 4*x-11*y=0
• 24*x^2*y^2+32*x^2+16*x*y+18*y^2=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
