How to Study for Math Tests
1. Go over the class notes — make sure you can do the class examples. 2. Go over the quizzes — do you know what you did wrong and how you could avoid those mistakes on the test? 3. Comb through your homework assignments. Do a variety of questions. Don’t forget to check your answers […]
Cosine Law
Remember for Cosine Law: Solving SSS –> calculate largest angle first. For SAS –> calculate third side, then smaller angle.
Radical Equations
Some of the homework questions require that you be able to factor ax^2+bx+c. If you forget how to do it, click here.
Multiplying & Dividing Radical Expressions
Rationalizing the Denominator:
The 3 Trig Ratios (ASTC)
Angles & Their Measure
In this video he uses “principle angle” while I called it “angle in standard position”.
Special Angles
Ms. Yang’s Full Lesson: In case you didn’t understand Ms. Yang:
Sine Law
Adding & Subtracting Radical Expressions
Radical Operations
Don’t forget to restrict the variables left in the radical. They must be greater than zero!
Simplifying Radicals
Simplifying Square Roots: Simplifying Cube Roots: Simplifying Expressions: The following video uses a different method than how I taught.
Ambiguous Case (for Sine Law)
**Just note that in class, I taught the Ambiguous case with the bottom left corner of the triangle as “A”, bottom right corner as “B” and the top corner as “C”. For these same corners, the videos below use “B”, “C”, “A”. Take a look at the java applet below. You may need to drag […]
Discussions
Leeman, how do I do this: If a student clicks on “Math 10”, I want it to bring up a page of possible links to go to: 1) Chapter 1: Measurement 2) Chapter 2: Trigonometry 3) Chapter 3 : etc 7) Discussions So when they click on “chapter 1: measurement” it will bring up a […]
