• Canonical form of a parabola

• How to use it?

• Canonical form:
• k=4x^2+2sqrt(15)xx+2x^2
• z=ln(x+y)
• (x-3)*(5-x)
• 4xy+3y^2+16x+12y+36=0
• Plot:
• y=-0,8x;y-2,5x;y=0,4x
• |y|=abs(sin(x))
• xy+x+y
• z=4*(x-y)-x^2-y^2
• ln(x+y)

• Identical expressions

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

• Similar expressions

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