I was thinking about saving my summer trip with my friends to Cedar Point until September. I would like to go on a Saturday when it is open 11-midnight so that we can stay longer. I have been to Cedar Point many times, but I have always gone in the summer, especially when my family gets in for free (military). I think it will be generally less crowded, but then again in September CP is only open on weekends. Does anyone think it would be worth it to lose an hour of ride time and go in September?

I was given cot x = - sqrt6 / 3.

pi/2 < x < pi.

I just want to check if my other 5 are right.

I got:

tan x = -sqrt6 / 2

sec x = -1/2

cos x = -2

csc x = sqrt3 / 3

sin x = sqrt3

I'm doing quiz corrections and I can't figure out what I did wrong on this problem:

"Write an equation for the inverse of y = 4 Arccot (3x/4 - 2/3)."

I did this:

1. x = 4 Arccot (3y/4 - 2/3)

2. x + 2/3 = 4 Arccot (3y/4)

3. 4x + 8/3 = 4 Arccot (3y)

4. 4x/3 + 8/9 = 4 Arccot (y)

5. x/3 + 2/9 = Arccot (y)

6. y = Cot (x/3 + 2/9)

I got a 2/5 on the problem and my teacher underlined a few things. First, he underlined in front of the "Cot," which is where I forgot to put +/-. He also underlined the "8/3" in step 3. And lastly, he underlined "x/3 + 2/9" in the last step.

Can anyone help me figure out what I did wrong? They are probably silly mistakes, but I just can't figure them out.

I've been debating on whether or not to buy the cd, In Vogue by Drop Dead, Gorgeous. Is it good? Is it bad? Or are there only a few songs worth getting? Or do you suggest another Drop Dead, Gorgeous cd more? (sorry for all the questions)
