reflection

I have to admit, this unit for me isn't that great. I'm not sure how to use some of the methods to solve the problems. I get how to finding the angle and the direction. The only thing that I think I'm going to have trouble with is the adding of the vectors and trying to find the place to put the vectors. But overall I think this unit is okay, not the best but it was the fastest unit so far.

Personally I found the unit on Vectors to be somewhat confusing. I don't feel 100% confident in using the different naming methods such as Direction Angle Direction. I am okay with using the Angle Direction of Direction. Also at first I was not sure where to place the protractor when measuring out an angle from a word problem. I am okay with this now though. Overall I found this unit to be a little more confusing than the stat unit.

REFLECTION!

Well the unit we were on was on vectors. I didn't really understand it at first. We had to review some of our trigonometry knowledge from years before. After the review I started to understand what we were being asked for. Since the program Trisolve2 was introduced to us, I started to understand more about the unit and help me figure out the sides and angle more. I found this unit to be a really short unit.

The vector unit was not too difficult. The beginning was easy like when we had to find the length using our rulers, then angle using our protractor, and just all 4 notations for writing a vector. Once we got to using the Pythagorean Theorem on vectors it was a little confusing for me at first, but I eventually got it. I like using "trisolve2" i think it is way easier to solving a triangle. I don't like the parallelogram method so much. I know I have to work on that.

Vectors

Soaring, flying, there's no star in heaven that we can't reach, if were trying, were breaking free. [8]

Sorry song stuck in my head just watched HSM again. Haha, so anyways, here is my blog after a 2 day rest, I already forgot what I was supposed to talk about even though I did write down notes on what I should scribe on today.

So on May 1st, which was last Friday, I was chosen by Iris (grr, don't like you =P), we had our last class of Vectors. Yipee! But which also means that there will be another test coming up which is on Tuesday. And tomorrow will be our Pre-Test, so everyone be prepared =). And also just a reminder don't forget to post your reflection for the unit Vectors.

Back to my post

So on Friday Mr. K finally finished the unit of Vectors, he also showed us another method aside from the Triangle Method. And it is called the Parallelogram Method, instead of having the vectors go from tip-to-tail. The Parallelogram Method goes from tail-to-tail.

This is how the Parallelogram Method is to be used:
















So anyways instead of 2 vectors being connected, there will be 3 vectors. Thus forming the parallelogram shape, and when you put another vector down the middle, it also forms two triangles. Also a reminder that when you are creating a diagram like this, make sure that the scale respects your diagram.

After that explanation Mr. K solved a problem with us, this problem was kinda confusing for me but it all worked out in the end, here it is:



















There really isn't much to explain any further, so all I gotta say is study hard and prepare for the Vectors test on Tuesday.

Next person I chose is Camilla for scibe! Haha.
