Section 8.1

We started to look at an alternative way of expressing lines, through the use of vectors.

HOMEWORK:  Page 433 - 434, #'s 4, 5, 7, 9 and 11

P.S.  Get back into the swing of things as we head into the final month of class.  Read ahead into section 8.2 in preparation for class on Friday.

Ch. 7 Review

It's been a while since we have made an entry to the blog...

Key concepts from Chapter 7 are:

• Vectors as forces
• Dot product of geometric and algebraic vectors
• Scalar and vector projections
• Cross product
• Applications of the dot and cross product

Here are the recommended review questions that you should try from Pages 418 - 421:

#'s 1, 2, 3, 4, 6, 7, 9, 12, 14, 15, 18, 20, 23, 24, 25, 27, 30 and 34

Now start studying!!!

Vector Projections

Below are the links to the videos that we watched in class today regarding Scalar and Vector Projections.

Use these along with the examples in your student text (section 7.5) to consolidate your knowledge on this topic.

HOMEWORK:  Page 399-400, #'s 4, 6, 7, 11 and 13

Algebraic Dot Product

Once again you are encouraged to read over the examples provided in your student text.  Pay close attention to example 5 on page 384 as it may prove useful in helping you answer some of the homework questions.

HOMEWORK:  Page 385 - 387, #'s 2, 6c, 7, 10, 12, 16 and 17

Geometric Dot Product

We looked at section 7.3 in class on Monday.

HOMEWORK:  Page 377, #'s 2, 6ab, 7a, 8, 9 and 11

NOTE:  We will be moving into section 7.4 tomorrow, this involves the dot product of algebraic vectors.

Velocity (Section 7.2)

Don't forget to read the examples from your text for this section.

HOMEWORK:  Page 369 #'s 3, 4, 5, 6, 8, 9 and 12

Vectors as Forces

We have started chapter 7.  Please, please, please read ahead.

HOMEWORK:  Page 362 - 364, #'s 3, 5, 7, 8, 13 and 17

Parking Lot

Just providing a clean spot in case any of you have any questions that you want clarified prior to the test on Monday.  I will check the blog at least twice this weekend.  Sometime Saturday night and sometime Sunday evening as well.

Operations with Vectors in 3-space

We managed to get through 6.7 in class today.  On track to finish chapter 6 tomorrow with a lesson on linear combinations and spanning sets.  UNIT TEST will be on MONDAY, May 7th

HOMEWORK:  Page 332 - 333, #'s 1, 2, 5 through 8, 12, 14 and 15

Algebraic Vectors in 2-space

We continued onto section 6.6 in class today.  The plan is to move ahead with 6.7 on Wednesday, so be sure to read ahead as always.
