preCalculus 2017-2018:
Laws Of Sines and Cosines
(November)
Chapter 8 ScreenCasts
Chapter 8 was all about Applications Of Trigonometry. First we solved Right Triangle using Pythagoras and SOHCAHTOA. Then we solved nonRight Triangles using the Laws Of Sines and Cosines. We even calculated triangular areas using Heron's Formula! We found that Law Of Cosines is great for SSS and SAS problems. Other cases used the Law Of Sines. Watch out for that Ambiguous Case! We had fun applying our advanced trigonometry to real world data and word problems. We even tackled Harmonic Motion and Sinusoidal Regression!
