Dear Readers,

I have procrastinated my Trig HW and I did what I knew but there are a few problems that I am stumped on and the Book does not do a great job on explaining it... So I shall see if you guys/girls can help me out.

Directions: Solve each equation on the interval 0 is less than or equal to theta(Symbol) < 2Pie.

11. 2Sin(squared)Theta - 1 = 0

13. Sin(3Theta) = -1

17. Sec 3Theta/2 = -2

23. 4Sec(Theta) + 6 = -2

-I got this down to: Sec(Theta) = -2

25. 3(Root 2)Cos(Theta) + 2 = -1

-I got this down to: Cos(Theta) = -3/ 3(Root2)

27. Cos(2(Theta) - Pie/2) = -1

29. Tan((Theta)/2 + Pie/3) = 1

I am sorry to put this onto you to help but yeah I just do not understand these problems but I got all the others...

If you are able to provide assistance I would appreciate like a tutorial on it to help myself... Thank you in advance.
