many questions

I have several questions, some are procedural and some are mathematical:
1) in the brief assignments page there are several quizzes listed such as week 2 quiz #1 and so on. since there are no links to these do we need to come in to highlands and take them?
@&
Each of those quizzes follows the link entitled Rand Prob, in the same line. You should click on that link. When you do you will find the quiz.
You should be submitting those quizzes. These quizzes are designed to prepare you for much of the Major Quiz.
*@
2) for the first major quiz, I am already almost finished with week four, can I come take the test anytime I want? and then just send you a test form telling you that I have done so?
@&
That is exactly what you should do.
*@
3) when studying for the tests and quizzes, I know you gave us a set of focus questions for the first major quiz, besides those would you suggest that I focus on the qa's and querys or the examples in your notes and the book?
@&
Under 'Testing' on your homepage menu you will find complete instructions for testing. Those instructions take you to the actual tests (which change every 5 minutes). You can view as many as you like.
*@
4) can I get a different calculator besides the casio approved for the quizzes/ tests? I use a TI-30X IIs. it is a basic calculator that I am already used to
@&
I can't investigate every calculator, so I confine the choices to one inexpensive calculator.
The reason for this calculator is that students can, and many do, put massive 'cheat sheets' on most calculators.
I do have an FX-260 to put in the test center, and should be able to do so tomorrow.
You'll mainly use the calculator to do simple but tedious arithmetic. The operations are straightforward and, especially since tests are untimed, this shouldn't cause anyone any problem.

5) could you possibly explain the radian circle a little more to me? it is very easy for me to just memorize the radians and angles but I do not understand how you get the radian for each angle? do you just add a certain amount for each angle?
@&
The basic ideas are simple enough.
There are 360 degrees around a circle.
And there are 2 pi radians around the circle.
If you multiply the number of radians in an angle by the radius of a circle, you get the arc length subtended by that angle on the circle. This is why there are 2 pi radians around the circle.
The radian is therefore a convenient way to relate an angle to the arc of a circle.
The radian is the default measure of angle. An angle of 30 means 30 radians. If you want the angle to be 30 degrees, you have to specify the degrees. You don't have to specify the radians if the angle is in radians, but you may, and it is often a good idea to do so.
*@
@&
Since 360 degrees = 2 pi radians, you can convert using either of the conversion factors
360 degrees / (2 pi radians) = 180 degrees / (pi radians)
or
2 pi radians / (360 degrees) = pi radians / (180 degrees).

@&
The trigonometry you should know by now is at my Precalculus II homepage. In particular, qa01 - qa08 contains information you probably don't have if you don't understand radians. You will need this information in calculus, and you should work through those qa's. You aren't required to do so, if you do you aren't required to submit them, and if you submit them (as you are welcome to do) you aren't required to do every problem.
I'll also note that you'll be running into radians very shortly in physics.
The Precalculus II assignments, containing links to the qa's, is at
