Summer School
Mid-Term Review Videos
Are Up and Running!
The long-awaited, much-anticipated Mid-Term Review Videos are finally online. Simply choose any of the videos below to study the online content. The videos are tapes of a Summer 2009 class, a special Algebra II Speed Review.
How to find the angles and Trig ratios for a right triangle
Solving a right triangle means finding the three, most-important Trigonometric ratios, Sine, Cosine and Tangent. It also means calculating the three angles in the triangle. Have no fear! The following three videos make it all clear.
Here's part 1 of a two-part lesson on solving a right triangle
Trigonometry students will find a lot of information packed into these three brief videos: everything from how the special triangles fit into a Unit Circle, how to figure out the Radian measures for these triangles and what it means to plot angles with negative or positive x-y coordinates.
The videos below were recorded on Friday, July 17 as part of an "Algebra II Speed Review," an attempt to cover a number of algebraic topics that will appear on the DCPS and Mr. Sanders's mid-term and final exams for our Summer School students. Half of these were uploaded on Saturday evening, July 18. The second half were uploaded on Sunday, July 19, before 4pm.
The videos are divided into topic segments covering the following:
Video #1 -- Properties of the Number Line
Video #2 -- Units of Measurement
Video #3 -- Degrees, Radians and converting between the two
Video #4 -- Domain and Range and the concept of Functions
Video #5 -- Functions, part 1: trade in "y" for "f(x)"
Video #6 -- Functions, part 2: equations are "function machines"
Video #7 -- Functions, part 3: functions and matrix math
Video #8 -- Scatter Plots and best-fitting lines
Videos #9-to-#11 -- Graphing a best-fitting line on a TI calculator
Video #12 -- Plotting a line given two points, and how to derive the linear equation
Videos #13-to-#16 -- Plotting linear inequalities
Videos #17-to-#18 -- Advanced Matrix math
Video #19 -- Solving a system of linear equations in four variables by using an inverse matrix
