In todays class we we were assigned homework on Exercise #4 questions 1-17(all). For this exercise we are to use factoring techniques from grade 10 along with what we learned about the unit circle.
If you forgot how to factor heres a website that will hopefully help: http://www.purplemath.com/modules/simpfact.htm
This site also explains how to solve quadratic equations; here is the link: http://purplemath.com/modules/solvequad.htm
If the sine and cosine in the equations on the homework confuse you remember that you can replace sine theta with y and cosine theta with x then solve the equation. Then when your done turn y and x back into sine and cosine and find the angle measure.
Good luck. (don't forget test on wednesday)
