In this week, we expanded our knowledge of Grade 10 trig. We started off by reviewing Grade 10 trig last week. We went through the formula SOH CAH TOA to remind us about the topic we learned. This week, we learned how to find the length and the angle of a special triangle that isn’t 90 degrees like the ones that we did when we were Grade 10. We learned about the reference angle, the quadrants where the angles located the negative and the positive sides of a triangle , finding the angle and the length with Sine law, and Cosine Law.
