This week in advanced math we started on chapter 12. We also delved deeper into the Aleks program. I absolutely hate that program because Im the type of person with little time, I dont have all day to sit at a computer because Im never home. In other words I miss blogs so bring them back and get rid of Aleks. But anyway back to chapter 12.

Vectors and Planes

-ax + by + cz+ d when ax + by + cz= d

|a,b,c| must be a vector perpendicular to the plane

3D graphing

-Perpendicular vector to a plane are said to be normal.

Ex. idk if this is right

Vector( 6, 5, -4) is perpendicular to a plane that contains A(0,1,2) Find an equation of the plane.

4x-5y+6x=24
