Conceptual Framework - Secondary Math Education Program - UMBC. The Framework The UMBC Secondary Mathematics Education program recognizes that teacher preparation is initial professional development (PD) and uses the Professional Development: Research, IMplementation, Evaluation (PrimeD) framework to structure activities in the program.

The PrimeD framework was developed through a series of research projects1-8. PrimeD is organized into four cyclic, interactive phases: Design and Development, Implementation, Evaluation, and Research. View Program Challenge Space References Saderholm, J.

How To Learn Trigonometry Intuitively. Trig mnemonics like SOH-CAH-TOA focus on computations, not concepts: TOA explains the tangent about as well as x2+y2=r2 describes a circle.

Sure, if you’re a math robot, an equation is enough. The rest of us, with organic brains half-dedicated to vision processing, seem to enjoy imagery. And “TOA” evokes the stunning beauty of an abstract ratio. I think you deserve better, and here’s what made trig click for me. Accumulated cross-sections - Ximera. Trapezoid - Geometry Calculator. Calculations at a trapezoid.

A trapezoid (or trapezium) is a tetragon with two parellel sides. Enter three side lengths and one angle between two of those sides. Choose the number of decimal places and click Calculate. Please enter angles in degrees, here you can convert angle units. Graphing Calculator. Affine transformation. An image of a fern-like fractal that exhibits affine self-similarity.

Each of the leaves of the fern is related to each other leaf by an affine transformation. For instance, the red leaf can be transformed into both the dark blue leaf and the light blue leaf by a combination of reflection, rotation, scaling, and translation. If.

Right-angled triangles with whole number sides have fascinated mathematicians and number enthusiasts since well before 300 BC when Pythagoras wrote about his famous "theorem". The oldest mathematical document in the world, a little slab of clay that would fit in your hand, is a list of such triangles. So what is so fascinating about them? This page starts from scratch and has lots of facts and figures with several online calculators to help with your own investigations. Ellipses and Elliptic Orbits.

Abstract algebra. Create LaTeX tables online. PCC Mathematics Home Page. Inner product. At the heart of digital signal processing is linear algebra, 'matrix algebra'. And at the heart of linear algebra is the inner product. Linear algebra is a huge area of research, most of of which I do not understand at all. Fortunately the inner product is a simple concept, and from there you can penetrate into deeper levels of the subject. On a previous page I illustrated how matrix multiplication is a matter of cutting the things into rows and columns and find the correlations of these vectors.

Here is a cut 'n paste from that page to refresh. Finding an inner product of vectors can serve various purposes: - you want to analyse the correlation of the vectors - or you want to manipulate the content of vectors The correlation of two vectors can be a positive or negative number, or it can be zero. Choose an arbitrary example for (a+ib): (0.8+i0.6).

It is zero. Projects of Zack Booth Simpson: math. Showing posts with label math. Show all posts. Section-WILA. Subsection LA Linear + Algebra The subject of linear algebra can be partially explained by the meaning of the two terms comprising the title. “Linear” is a term you will appreciate better at the end of this course, and indeed, attaining this appreciation could be taken as one of the primary goals of this course. However for now, you can understand it to mean anything that is “straight” or “flat.” For example in the -plane you might be accustomed to describing straight lines (is there any other kind?) As the set of solutions to an equation of the form , where the slope and the -intercept are constants that together describe the line. Matrixology, Season 8.

Error bound for a perturbed minimization problem related with the sum of smallest eigenvalues Marcos Vinicio Travaglia. Graphical Linear Algebra. So far we have not discussed categories in any depth. The reason for this is that I wanted to give you a feel for working with diagrams, for which we do not really need any deeper theory. Commutative Rings and Fields. Different algebraic systems are used in linear algebra. The most important are commutative rings with identity and fields. Definition.
