 * 1) 2 and #4 done by: Frances Dannenbrink

I got those right. Checked by Angie tutia

Done by Emily Johnson  I got both of those answers as well! -Blake Schreiber
 * 1) 6 & 8

Done by Andrew Kim
 * 1) 10 and 12

10 and 12 check by Matt Bogaert I got the same answers.

Done by:Valeria Chelala is (7π/6) and (11π/6) because it is not an inverse problem Checked by: Leslie Baker
 * 1) 14 and 16
 * 14:same
 * 16: i got π, 0, (π/2) Which those are right but instead of (-π/6) i got:

2=3sin2x+1 1=3sin2x 1/3=sin2x 1/3=2sinxcosx 1/6=sinxcosx sinxcosx=-√2/4
 * 1) 18. 5sin2x+2=8sin2x+1
 * after this I wasn't sure what to do.
 * 1) 20. 4sinxcosx=-√2
 * I had the same problem on this one...
 * 1) 18-20 Done by: Kamryn Richard

For #18 I don't think I did it right but i didn't change the sin2x to sinxcosx and i eventually got to 0=3sin2x-1, when i brought everything to one side and set them both = to 0 so i got 0 but i am not sure because i dont know how to distribute sin2x. For #20 I had a lot of trouble, i got to same point that you did but i still dont know how to distribute sin2x.

18-20 checked by Emma McRae- sorry i am so late i did not get home until now


 * 1) 22 and #24



I didn't come to the conclusion that there was no solution to #22. I found that x=1-√2, so I plugged it into my calculator and found that x=1.998

I arrived at the same conclusion for #24.

I wasn't too sure about #32/34 Done by Jonathan Eichelberger I got the same answer for 30 and 34, i was confused on how to do 32 also, but it looks good work wise, got confused on what to do after u do after the quadratic though to find the X
 * 1) 30 - 34
