• How to use it?

• Canonical form:
• 2x(1)^2-2x(2)^2+x(3)^3+16x(1)x(2)+4x(1)x(3)
• 3x^2+0xy+4y^2-6x+16y+7=0
• x^2+4*y^2+2*x-32*y+64=0
• x^2-2x+10y+21=0
• Plot:
• x^2/9-y^2/4=1
• x^2/3+y^2/5-1=0
• y-x*ln(y/20)-100=0
• x2-2*x+y2-2*y=2

• Identical expressions

• y=ln*(x+y)
• y equally ln multiply by (x plus y)
• y=ln(x+y)
• y=lnx+y

• Similar expressions

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