Work Period

Today was a work period, I went over everything and I feel pretty confident about this test. My only problem maybe would be with graphing but I will just keep looking at that one. I also took a second or two today to look at the world cup qualifiers, France (my team) just has to beat Ireland twice they should be fine. Just thought I would let everyone reading know that.

Double Angle Identities

We learned about double angle identities today. They are the same as sum and difference really just an alternate formula. The only real problem with these I can think of is getting the question in the proper form. Other than that I really have no problems with it!

Alpha and Beta Formulas

We went over the alpha and beta formulas today, I found that they really help solving sine and cosine values. The only problem would be remember the signs.

Proofing Identities II

There was no new assignment today, and we basically went over more examples today, I got through some of the assignment and I will tackle the rest of it tonight!

Proofing Identities

Today we learned how to prove identities, I didn't really understand what he was doing at the start but I slowly caught on. One thing I believe might help for me is if I swap out a "Y" value for say cos(x). This would only work however if I remember what is in place for what. I am a little behind in class right now, but with soccer over now I will have lots of time to catch up.
This was also on the wrong blog, just fixed it now.

Graph Compressions.

Today we learned about graphing with absolute values. For example y=|x| will give you a V, 1/3|x| will make it narrower and 3|x| will make it narrower. Also if you put the B value in the | | it does not change the graph. so 3|x|=|3x|.
