How to use it?
Canonical form:
x^2 – 8x – 4y=0
(x^2)/4+(y^2)/36+(z^2)/25=1
9x^2+16y^2-18x+128y=-121
4x^2+4y^2-z^2+16x-40y+116=0
Plot:
e^(y/x)=x*y+1
tan(x)=sin(y)+cos(y)
sin(y)+sin(x)=1
-x2*y3+3*(x2+y2-1)=0
sqrt(9-x^2-y^2)
Identical expressions
sqrt(nine -x^ two -y^ two)=z
square root of (9 minus x squared minus y squared ) equally z
square root of (nine minus x to the power of two minus y to the power of two) equally z
√(9-x^2-y^2)=z
sqrt(9-x2-y2)=z
sqrt9-x2-y2=z
sqrt(9-x²-y²)=z
sqrt(9-x to the power of 2-y to the power of 2)=z
sqrt9-x^2-y^2=z
Similar expressions
sqrt(9-x^2+y^2)=z
sqrt(9+x^2-y^2)=z

sqrt(9-x^2-y^2)=z canonical form

The teacher will be very surprised to see your correct solution 😉

\/  9 - x  - y   - z = 0

$$- z + \sqrt{- x^{2} - y^{2} + 9} = 0$$

-z + sqrt(-x^2 - y^2 + 9) = 0
