Hello, guests of Mathland!
This week, we had trig review week which went back to our trig identity proofing.
To start off, we began with simplifying the trig expression in order to make the problem easier to do. After that, we verified (or proved) each identity - meaning we proved that the left side equaled the right side.
To do such a thing, we used a trigonometric identity sheet that had all the identities on it:
Learning these identities again were a bit difficult, as these were taught near the beginning of last semester. However after a bit more practice, it was easier to do!
Below is an example of simplifying a trig function:
Below is an example of proving a trig identity:
That is all for today, good bye! See you next time!~
