Ways to Graph in 3D
- Planes parallel to the plane xy have z = c (constant).
- Planes parallel to the plane xz have y = c (constant).
- Planes parallel to the plane yz have x = c (constant).
- Equation of plane is ax + by + cz + d = 0.
Example 1 :
- Sketch the graph of z = -x-2y+2 = f(x,y).
- Solution :
- Let z = 0 and you get y = -x/2 + 1.
- If x = 0, then y = -0/2 + 1 = 1.
- If y = 0, then x/2 = 1 therefore x = 2.
- Let x = 0 and you get z = -2y + 2.
- If y = 0, then z = 2.
- Let y = 0 and you get z = -x + 2.
