Week 16 in PreCalc 11

On our first week back, we started and finished our trig unit. Last year, I didn’t like trigonometry at all, it was my least favourite unit, mainly because the whole idea of “SOH CAH TOA” confused me, but thankfully this year, I got a much better understanding of it, especially because we will be doing…

The Magic of Light – Physics 11

I chose a video called “Just Add Water,” basically there is a clear cup filled with water and behind it lies a white piece of paper with a drawing of some sort on it, let’s use one of the examples in the video, there was a word that spelled “now” and when the water was…

Week 15 in Precalc 11

This week in Precalc, we continued our unit on “Rational Expressions and Equations.” I actually am really enjoying the unit. We reviewed adding and subtracting Rational Expressions and I want to review the ones with non-variable and variable denominators. The first step is to determine the lowest common denominator (LCD) Then you rewrite each fraction…

Week 14 in Precalc 11

This week we finished our unit on Absolute Value and Reciprocal Functions and we started our unit on “Rational Expressions and Equations.” I enjoyed the unit on Absolute Value Functions because even though we continued on with graphing, it was still different than any unit we’ve done before and learning about asymptotes was so interesting…

Constructive Interference vs. Destructive Interference

Constructive Interference is when two or more waves that have the same frequency meet in a way where their crests line up together, basically overlap. Destructive Interference is when the crest of one wave meets the trough of another wave and they “crash” into each other, it results in a lower amplitude.

Week 13 in PreCalc

This week in math, we started our unit on absolute value functions. We used our knowledge from our absolute value unit from the beginning of the year and just added onto it with the knowledge we had from graphing, from the most recent units. So far, we learned the difference between graphing absolute values compared…
