### Computer Class

Wednesday, September 30, 2009

Today in class we went to nlvm.usu.edu.
To Learn about Geometry , We were learning about Transformations - Composition, Transformations - Reflection, Transformations - Rotation, Transformations - Translation.

What I learned was Inverse of transformations. And also about The Efficiency. And How to transform things in composition .

In Reflection I learned that The same picture is equal distant from a line of reflection.And that Segments joining corresponding sides of an object and image are perpendicular to the reflection line. corresponding angles and sides are congruent. Rotaions About the Orgins include

half turn clockwise or half turn counterclockwise .

In rotation i learned that is is It is important to understand the frame of reference . a coordinate rotation can be defined by three Eular anlges, or by a single angle of rotation and the direction of a vector about which to rotate. And also that rotation in 2 dimensions is commutative, unlike in higher dimensions.coordinate rotation which rotates the time axis is called a boost

In Translation I learned Original objects continue to be dynamically translated, The first original is visually connected to its image by the translation vector. When another object is placed on the workspace, its translated, When you first started Graphing Quadrants, you started with the basic quadratic, A function transformation takes whatever is the basic function f(x) and then "transforms" it or "translates" it, which is a fancy way of saying that you change the formula a bit and thereby move the graph around..

I learned A Few things from The Book Also , including The Site Mr. B Gave us !

Breann this is a better post than you ever did for me last year!! Great Job. You could improve it by adding labels to your post. You need to add your display name Breann906, and the unit of study Geometry etc. Nice job otherwise!!

Hey Breann this post is really cool i like that you added links and everything and the pictures were marvelous. But one thing though, you sorta have to watch a little bit of the spelling and some of the typos but overall this is great!

Wow Bre, good job on the post!I can tell that you put a lot of time and effort into this post. I like how you added the links, the colors, and the pictures. Keep up the great work, Bre!!! =)

Good job breann.... you actually did your post and it looks great... Good Jod.. Give yourself a pat on the back...:)
