• How to use it?

• Canonical form:
• 9*x^2+18*x+18xy+22y+13y^2=11
• 9x^2-25y^2-36x+100y-289=0
• k=4x^2+2sqrt(15)xx+2x^2
• z=ln(x+y)
• Plot:
• (x^2+y^2-1)^3=x^2*y^3
• sqrt(2-x^2)=sqrt(2-y^2)
• z=4*(x-y)-x^2-y^2
• z=/sqrt(3*x+2*y+2)
• ln(x+y)

• Identical expressions

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

• Similar expressions

• y=ln*(x+y)
• ln(x+y+z)=2
• z=ln(x-y)
• z=ln(x+y^2)
