Course Summary
Congratulations, you’ve completed Mathematics 20-2!
You enhanced your knowledge of geometry in Modules 1 and 2. You learned to use both the sine and cosine laws as ways to make indirect measurements. You also learned to use logic to prove conjectures about lines and angles. You learned to use both deductive and inductive logic to solve problems.
You learned about quadratic functions in Module 3. You worked with three different forms of quadratic functions and converted between them. You modelled real-world situations using quadratic functions and used your graphing calculator to assist you.
You learned about statistics and how statistical data can be used in quality control in Module 4. You learned about ways to predict the confidence you should have about data you or others collect.
You used radicals to solve problems in Module 5. You explored different methods of solving radical equations and saw that sometimes there were extraneous solutions introduced by the solution methods. You saw that these extraneous solutions were related to the domain of the original equation.
You worked with proportional reasoning in Module 6. You used equivalent ratios, unit analysis, unit rates, writing functions, and drawing graphs to solve problems. You used proportional reasoning to find areas, surface areas, and volumes of similar objects when the scale factor was known. You also found scale factors for various shapes of objects.
In Module 7 you completed a research project about a topic you had studied in the other modules.
You should now contact your teacher to ensure that you have completed all requirements and to find out if there are other assignments or tests that you have to complete to gain credit for this course.
