Yo, Whats up guys?! Adrian here

      Since its late start today, we had a short class in Pre-Calculus.There was a background picture with a squirrel in Mr.P's Computer, but he didn't explain how he took the photo and what happened to that day like he usually do. Then he talked about how people who participated in this blog will get bonus points and described how to use it.Though, we cant apply the bonus points in the final exam. He also talked about "10/10/10 article ", and he said he was going to bring this article  next class.

     Anyways, during our class time, we studied about Transformations on Sine and Cosine Functions(how the graphs of y=sinx and y=cosx move around the graph.

(Note: y = asinbx is the same as y = x^2, and y = asin(x-c) + d is the same as y = a(x-h)² +k)

Example:
           
     y = 2sinx

 

X	Y
0	2.2=0
90o	2.1=2
180o	2.0=0
270o	2(-1)=-2
360o	2.2=0
