• How to use it?

• Canonical form:
• 4*x^2−12*x*y+9*y^2−20*x+30*y+16=0.
• (x^2)/6-(y^2)/4-(z^2)/1=0
• x^2-8xy+7y^2
• x^2-2xy+y^2+10x-6y+12=0
• Plot:
• z=3*x+6*y-x^2-x*y+y^2
• 3cos(2x)-x+0,25=0
• y^4-x^4=x*y
• log(|x|)-log(|y|)=1
• 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
