During this next part of our study of vectors, we will first look at how to multiply vectors with the scalar product (dot product) and also take a good look at how we can use vectors to represent straight lines either on the plane or in space, and also look at what we can do with those lines.
Thursday, 3/3 - we looked at when vectors are parallel and how to create vectors facing in certain directions from unit vectors. Here are the slides from class. Your HW is p. 416 (Ex. 9.3) #5-6, 8-10 & #25 as an optional challenge.
Friday, 3/4 - we looked at the definition of the scalar (dot) product. Here are the slides from class. Your HW is p. 424 (Ex. 9.4) #1abc, 5a, 12, (optional challenge #11) & p. 642 (Ex. 14.2) #1ab, 2, 16.
Monday, 3/7 - we looked at some properties of the scalar (dot) product. Here are the slides from class. Your HW is p. 424 (Ex. 9.4) #3, 10 & p. 642 (Ex. 14.2) #7, 8, 19, 26.
Tuesday, 3/8 - we did practice problems involving the scalar (dot) product. Here are the slides from class. Here is the HW from class, the hot pepper problems.
Wednesday, 3/9 - we looked at how we can use vectors in real world applications. Here are the problems from class, and your HW is #3-5 on the back of that sheet.
Thursday, 3/10 - we started to look at how to represent lines in the plane with vector equations. Here are the slides from class and here is the packet of notes from class that includes your HW. Your HW is the backside, #1-4.
Friday, 3/11 - we looked at the angle between two lines. Here are the slides from class and here is your worksheet which is for HW.
Monday, Pi Day - we looked at vector equations of lines in space (3D). Here are the slides from class and here is your HW worksheet (four problems on the back) that includes some notes from class.
Tuesday, 3/15 - we're looking at how we can apply vector equations of lines to problems that involve constant velocity. Here are the slides from class. Here are the problems from class. Your HW is p. 667 (Ex. 14.4) #12 and p. 426 (Ch. 9 Practice Questions) #8.
Wednesday, 3/16 - we looked at how to determine if two lines are parallel, coincident, skew, or intersecting. Here are the slides from class. Here is the worksheet from class with your HW on the back, #1defg, due Friday.
Thursday, 3/17 - we have a half day today because of Discipulus Led Conferences.
Friday, 3/18 - we continued to practice the the relationships between two lines, and in particular looked at how we can determine if two particles moving along two different vector equation lines will collide. Here is the problem from class. No HW tonight.
Monday, 3/21 - we did IB style problems in preparation for our quiz tomorrow, which is on the dot product, parallel vectors, writing vector equations of lines, and determining how vector equations of lines interact with each other (parallel, coincident, intersecting, skew). Here are the problems, with solutions, from class.
Tuesday, 3/22 - we have a quiz on the dot product, parallel vectors, writing vector equations of lines, and determining how vector equations of lines interact with each other (parallel, coincident, intersecting, skew).
