Main Topics and Formulas

[Calculus98]

TMSCA State is in a few days and I was wondering what the main formulas I should be practicing are? I know that the problems normally use a modified form of the exact formulas, but what are the main things to know?

Thanks

Could you be a bit more specific? I don't really know what you're going for here. Also, there are LOTS of things so it would be hard to tell you specific things instead of just general topics.

What are the formulas for interest? Fibonacci and Lucas formulas? How to find the distance from a line to a point? How to calculate bearing problems? Finding the inverse of a matrix? Main probability formulas? What is the complement of a set?

Sorry if this is a lot, but I want to make sure I am ready for this weekend.

For simple interest, [unparseable or potentially dangerous latex formula].

For interest compounded n times per year, the equation is [unparseable or potentially dangerous latex formula].

For continuously compounded interest (take the limit of the above equation as n approaches infinity), [unparseable or potentially dangerous latex formula].

For Fibonacci and Lucas numbers, there are a LOT of formulas. I suggest you Wikipedia them.

The distance from a line to a point... well the distance from a line [unparseable or potentially dangerous latex formula] to the origin is [unparseable or potentially dangerous latex formula].
If the point is not the origin, you could translate the line and the point so as to get it go the origin. For example, if you had the point (4,3), find the distance from the line [unparseable or potentially dangerous latex formula] to the origin. I think that would work.

Bearing problems are vector problems. A bearing of an angle [unparseable or potentially dangerous latex formula] means you travel, relative to the +x axis, at [unparseable or potentially dangerous latex formula]. So add 90 to all of your angles. To find the final point which the object moving is, break up the vectors into components (I can show you this later.)

To find the inverse of a matrix (if it exists), put the matrix in your calculator and put it to the -1 power.

Probability is usually basic formulas (at least on this test) and figuring out how to apply them. You already know the formulas, so you'll just have to get enough experience to where you know how to solve different types of problems.

If you have a universal set [unparseable or potentially dangerous latex formula] which is basically the set of all elements you are "allowed" to use, and then a set [unparseable or potentially dangerous latex formula] that contains some elements from U (and no others, since U is the universal set in the problem), then the complement of S is the set of all elements in U that are not in S.

Hey
Math has a wide range of topics that cannot be covered just by a few formulas.
It requires a lot of knowledge about math itself.
There are many shortcuts to problems and I doubt you can learn it in one day...
I mean interest, matrices - OK
but theres so much more!
I think - calculus98 - u better just relax
If you want, go over the math topics you have covered at school - I mean you can do most of the problems with that knowledge itself.
Like geometry - theres at least 1 q on this every test
then - probability - OMG - wide range - easy to understand but a lot to learn
nsguy has taught u wat u need so u should be fine on saturday
