• How to use it?

• Canonical form:
• 16x^2+24xy+9y^2+4x+3y=0
• x^2+y^2-z^2-2*x-4*y+6=0
• 3x^2+2y^2-6x-12y+22=0
• 3x^2+2y^2+z^2+4xy+4yz
• Plot:
• 2*y-3*x-1=0
• 10*x+5*y+15=0
• (x^2+y^2)^2=a^2*x*y
• z=x^4+y^4-2*x^2+4*x*y-2*y^2
• ln(x+y)

• Identical expressions

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

• Similar expressions

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