Using the Unit Circle for Simple Trig Questions
In this video I solve a three part question (3 problems actually) which can easily be done using the unit circle. This is an essential skill but when this was posted on several help groups nobody else even tried to answer. Some thought the question was advanced. (It's not.) I have handed in many engineering and physics exams with small circles in the margin where I applied this approach for a quick step in a much longer problem.
If you need help with things like this don't hesitate to contact me! I have been helping students from Grade 5 through complex analysis and nonlinear dynamics. I can also help with SAT and placement or admissions exams such as the Oxford MAT. My rates are below what many students charge.
