Today was the Vector Lab. We worked on the lab with our partners.

The lab with write up is due tomorrow.

You need: 2 vector analysis sheets with analysis completed.
1 write up explaining your methodology and your description of how things went.

Each school day it is late is a deduction of 10% up to a maximum of 30%.

Assignment P. 336 # 1 - 5.

Vectors Lab day is Tomorrow.

Math 9, Mar 30th

We started manipulating formulas today to solve for the other variable. It was challenging.

Apps 12, Mar 29th

We learned to add vectors using the parallelogram method. We worked with the cosine and sine law. We worked with two types of bearing notation ( 120 deg or E 30 S). It was challenging.

After lunch we worked together on an example of a vector lab type question.

Vector Lab on Wed Mar 31st.

Vectors Test, Tuesday April 5th.

Math 9, mar 29th

Assignment P. 129 # 3, 4, 5, 6, 8.

Apps 12, Mar 25th

Today we talked briefly about the project for this chapter. I described an example but I did not work through it completely as we have not covered some of the necessary math yet. Then we worked on multiplying vectors by scalars. The key element was using a good scale for your original vector and measuring it with a ruler. Then all the other vectors could be drawn by using your scale to convert them into a length. We also used the other edge of the ruler to keep our lines parallel.

Assignment P. 322 # 1 - 5.
Assignment. I handed out a worksheet in class. It can be found here.

Calculus, Mar 25th.

Here is the weekend related rates assignment. Worksheet.

Please hand it in on Monday.

Calculus, Mar 24th

Today we started related rates. We worked on basic problems, discussed taking implicit derivatives when they variable does not appear in the equation (with respect to time for example) and then looked at some problem types.

Assignment P. 202 # 1, 3, 7, 9, 15, 19, 23, 25, 30, 31.

Hand in Assignment. # 27, 34, 35. Due Monday.

Test will be next Tuesday.

Today we discussed adding vectors using the pythagorean theorem and trigonometry. It was challenging so we will be doing more of it tomorrow.

Assignment. There was a package of questions handed out in class.

Math 9, Mar 24th

Today we looked at Distance/Rate/time problems. We mostly worked with basic conversions however at the end we talked about chase and total distance problems.

Assignment P. 127 # 1- 25.

Apps 12, Mar 23rd

We started in the morning reviewing trigonometry. This assignment is not due.

In the afternoon we worked with adding vectors using scale diagrams.
We talked about the difficulty in using the blocks on graph paper as your unit of measure. We decided it was better to measure everything in centimetres.

Assignment P. 318 # 1- 9

Math 9, Mar 23rd

Started with a let statement quiz.

Reviewed word problems and made some of our own.

Assignment, P. 116 # 10, and four other questions of your choosing.

Assignment P. 195 # 1, 7, 9, 11, 13, 15, 17, 23, 31, 33, 45

Test will be next week on Tuesday.

Apps 12, Mar 22nd

We started by discussing scalars and vectors, we discussed types of values that could be in each category and then we worked on notation. We also discussed bearings.
