16. Convert your answer to standard form. 17. Find the three cube roots of 1. Hint: one of the the solutions is 1. 6. Solve for x : 2 sin?(x) - 1 = 0 in the interval [0, 27) 7. Solve for x : 2 sin(x) cos(x) - sin(x) = 0 in the interval [0, 27) 8. Simplify: tan?(x) (1 - sin?(x)) 9. Add and simplify: 1 + cos(a) 1 - cos (a) 10. Multiply: (4 - 2i) (4 + 2i)ll. Solve for as and write your answer in standard form: .762 8:6 + 20 : 0 12. Find |1+i| 13. Find the argument of 1 | i, that is, nd 0 14. Use your answers above to write 1 + i in trigonometric form7 i.e write 2 27E : 7' (GOSH?) + 'L' sin(9)) 15. Use the trigonometric form to raise l | i to the power of 4, i.e. F ind: (1 + 7;)4
