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 !
