An intuitive way to express the equation for a plane in Cartesian xyz space is to define the direction of a vector normal (perpendicular) to the plane, and then to identify the coordinates of a point in the plane We don t have to know the magnitude of the vector, and the point in the plane doesn t have to be the one where the vector originates UCC128 Scanner In Visual C#.NET Using Barcode scanner for Visual Studio .NET Control to read, scan read, scan image in .NET framework applications.

General equation of plane Figure 171 shows a plane W in Cartesian threespace, a point P = (x0,y0,z0) in the plane W, and a vector (a,b,c) = ai + bj + ck that s normal to plane W The vector (a,b,c) originates at a point Q that differs from P, and which is also located away from the coordinate origin The values x = a, y = b, and z = c for the vector are nevertheless based on the vector s standard form, as if it originated at (0,0,0) The point and the vector give us enough information to uniquely define the plane and write its equation in standard form as Making Bar Code In ObjectiveC Using Barcode generator for iPhone Control to generate, create bar code image in iPhone applications.

Plotting a plane When we want to construct a plane in Cartesian xyz space based on its equation, we can do it by figuring out the coordinates of points where the plane crosses each of the three coordinate axes These points are the xintercept, the yintercept, and the zintercept When we plot these intercept points on the axes, we can envision the position and orientation of the plane There s a potential hangup with this scheme for planegraphing Not all planes cross all three axes in Cartesian xyzspace If a plane is parallel to one of the axes, then it does not cross that axis, although must cross at least one of the other two If a plane is parallel to the plane formed by two coordinate axes, then that plane crosses only the axis with respect to which it is not parallel An example Suppose that a plane contains the point (3, 6,2), and the standard form of a vector normal to the plane is 4i + 3j + 2k Let s find the plane s equation in the standard form given above To begin, we know that the vector 4i + 3j + 2k is equivalent to the ordered triple (a,b,c) = (4,3,2) Surfaces in ThreeSpace
We ve been told that (x0,y0,z0) = (3, 6,2) and that this point lies in the plane The general formula for the plane is a(x x0) + b(y y0) + c(z z0) = 0 Plugging in the known values for a, b, c, x0, y0, and z0, we get 4(x 3) + 3[y ( 6)] + 2(z 2) = 0 which simplifies to 4x + 3y + 2z + 2 = 0
