Hey guys its Alvin. Sorry for the really late blog. Ill try to post what happened in class that day and hopefully be able to help you.
The first thing we learned was sin^2X + cos^2X = 1 (X = Theta).
This is also similar to the Pythagorean Theorem.
a^2 + b^2 = c^2
a = sin
b = cos
c = 1
This equation states that sin^2X + cos^2X can also be called 1. It also works the other way around; as for 1 can also be interpreted as sin^2X + cos^2X.
*From pc40sf07 slide oct. 22, 07.
The corollaries are like the sin^2X + cos^2X = 1 meaning that the left equations are equal to theyre right side. as for the right equations equal the left side.
In conclusion, this is about everything i remember from monday. Except from the group work that we did, if you are interested though it is on our oct. 22, 2007 slide. With this problem of mine, i believe that our study group would prove as a great asset. i just hope that I make sense of most of it before we go any more farther.
*I like the sine dance =) btw.
