LESSON 26 – EQUATIONS OF PLANESSeptember 4, 2013
Fernando Morales
PEER INSTRUCTION
Coincident: 1. Occuring together in space or time 2. In agreement or harmony
3. The two lines have all equal points
Answer:If they are scalar multiples of each other, then they are coincident.In this case since we can multiply all the terms in first equation by six, we obtain the second equation. Hence all points will be equal between the two lines.
MOVE AROUND!
Go around the classroom and answer the questions on the wall.
Use technology to assist you in checking the answers.
PEER INSTRUCTION
How can we define a line in two-space? How can we define a line in three-space?
[C] In both cases all we need is either two
points or a point and a direction vector.
PEER INSTRUCTION
How do we uniquely define a plane in three-space?
[C] To uniquely define a plane in three-space all
we need is either three non-collinear points or a point and two non-parallel direction vectors.
