Or 5 cubed divided by your longest ass hair times 2. It sucks.

ahh, see this is part of your problem.
aside form being an idiot that isn't willing to slow down and look at the problem - your variable names are all screwed up.
that and in order to solve for these, you need to have the equation equal to something.

so let's say we want to find the value of "my mom" in that first one. it is just as easy as the one that supersizeme posted.
3*(sr6^2)/myMom (from your wording, it isn't clear if the square root of 6 is raised to the second power - which would then negate the square root - and then divided by my mom - or if the 2 is divivded by my mom)

now that this is broken down, the way I wrote it above, it is (3*6)/(myMom) = unknown - let's say unknown is X.
If we then solve for my mom, that means we have to multiple both sides then by my mom, so that negates my mom on the left side, - leaving 18=X*myMom.
you can then multiply 1/X on both sides so that it gets negated off the right and sent over to the left. thereby, according to your formula, my mom is equal to 18/X. that means that as X approaches infinity, my mom approaches nil, and as X approaches zero, my mom approaches infinity.

I can solve the other one for you too if you want - but they are always easier if you have a better equation.

Picture a right angle triangle.
The height is 10inches.
The length is 10inches.
What is the length of the diagonal line?

I need to know the formula. I havent taken a math class in years,...

come on! this is the most basic trig.
okay, A^2 + b^2 = c^2
so 100+100=c^2
c = 14.142135623730950488016887242097
so the square root of 200 is what you are looking for.
there are standard ones like 3,4,5 and stuff like that.
if you want to know the area, it is each side times the other, and then divided by 2. yours in this case is only half a perfect square, so that is easy.

always 3,4,5 or a varient using the ratio

for any triangle:

the variant is either the sine rule or the sosine rule

sine rule

a/sin A = b/sin B = c/sin C

where a, b and c are sides of triangle and A, B and C are angles

if u don't have the info needed for this

cosine rule

a squared = b squared + c squared - 2*b*c*Cos A

oh. sorry. my bad.
how's this:
"just check out the girls while you're dropping ass because you slept with the teacher"
or
"sleep with your ass and drops girls like your teacher"

My degree is in mathematics. You are not making my existence easier.

jesus, I sound like my grandfather.

When you take advanced stuff like Calculus II or the shit that I'm taking now (Discrete Mathematics), you'll wish you had that Algebra to fool with.

If the complement of B is a subset of the complement of A, show that A is a subset of B. Have fun with that one. It raped me on my quiz today.

Don't worry about memorizing formulas, they should, key word should, give you the formulas on the test. My teacher gives us the formulas b/c he believes in real life situations you can always look up the info if your unsure, so instead of doing what most teachers do [make us memorize the shit] for the test he makes highschool be what its supposed to be. A microcosim [think thats the right word] of society. If thats the wrong word its supposed to mean a smaller version of the real world.

I have no advice to give ya, but to keep doing the type of problems over and over till it becomes second nature.

i take it then my suggestion about eyestrain is really obvious. It took our class a whole year to figure out the reason why that guy kept falling asleep (and as we matured why his eyesight seemed to get worse and worse )

I think I would have gotten a lot more out of it if I wasn't in a haze the whole time.

Garza, to many people struggle with math because they TRY TO HARD. It isn't about studying, it is about opening your mind and examaning the problem. Do the homework, read the book, and when it comes test time don't try and remember any of it. Look at the problem and discover your own answer.

peace.

Puc

Take a different class! hahaha.

If you can't get motivated to learn something in school - look around. who makes more money? the people that have the skills to do something nobody else can do - or that very few people can do.
in order to know more than someone else - you have to learn something along the way.
math is one way to do it.
