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…

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 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.

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…

Part Two: History Where was it invented: The arch bridge was invented in the piers, in the Pons Fabricius in Rome (It is still standing) Who invented it: Basically, the ancient Romans invented the arch but they originally learned the “arch” from the Etruscans and then just changed it up, refined it and were…

This week in math, we finished out unit on Graphing Inequalities and Systems of Equations, even though I struggled with a few of the lessons, I really did enjoy the unit, I thought it was interesting and it definitely added on from last year (shading, finding more than one solution, introducing parabolas, solving algebraically). I…

This week in PreCalc, we started our new unit on Graphing Inequalities and Systems of Equations, so far, I actually really like the unit, it reminds me a lot of what we did last year, it’s very similar but we expanded, of course, but even then, I like how when you figure out the equation,…

This week we didn’t really learn anything new, our main focus was reviewing for the midterm coming up so this week, for my top 3 things I decided to review, I just had a list of random questions I would study for the test so I just picked 3 different questions, all from different units….
