Jojo states that "it's really a crazy puzzle but there's a method to the madness" -which was exactly what we began doing during class.
Jojo first showed us the strategy that uses:
VERIFYING IDENTITIES: 1 + sex(x) sin (x) tan (x) = sex^2 (x) -->(this is the identity and now you must verify it)
Step 1: Start with the most complex side and work towards the easier side.
1 + (1/cos(x)) (sin (x))(sin(x)/cos(x)) --> here we turned everything into sine and cosine)
Step 2: Divide everything by the cosine --> sin^2(x) + cos^2(x) = 1
1 + (sin^2(x)/cos^2(x)) --> 1 + tan ^2(x) --> sec^2
-If you didn't notice there are a lot of Reciprocal and PT identities--this shows us how important it is to really have the identities down-
We then went over Identifying the Factor for the different of squares:
The first thing we covered in this section was:
FOILING: any time you have (a^2 - b^2) it also equals (a - b) (a + b)
The second thing we covered in this section was:
PERFECT SQUARE BI or TRINOMIALS: (we couldn't figure out if it was bi or tri)
(a + b)^2 always simplifies to a^2 + 2ab + b^2
We were about to begin figuring out the RATION EXPRESSION but it was time for Monday Morning Meeting.
I am terribly sorry for this scribe hold up, i promise never to do it again. I hope that my scribes from last week are helpful to anyone who may need it.
The next scribe is..zoe
