So, I was recently think about something. Don't ask me how I thought of this, but positrons and anti-protons were on my mind all day and I thought of something. I thought about inertia. I thought about it and the more and more I did I figured that there must be something within matter that makes...
Homework Statement
Simplify:
2csc^2 - csc^4 + cot^4
Homework Equations
The Attempt at a Solution
2(1/sin^2) - 1/sin^4 + cos^4/sin^4
So here, i figured that if i re-write them, that maybe it will leave me more options, but I dont see anything that will cancel out. Then i...
Homework Statement
Mnimize and maximize:
P=30x + 10y
Subject to 2x + 2y > or = 4
6x + 4y < or = 36
2x + y < or = 10
x, y > or = 0
Homework Equations
The Attempt at a Solution
How would I go about graphing this on my calculator: 2x + 2y > or = 4...
yeah but when you plug that in how do you know what to plug for the variables to get the correct number for the variable. You could be plugging in two numbers that give you remainder of 0 but dont give you what the actual value of the variable unless you get 0 on the other root also. Is there a...
the roots they give you are (x-1) and (x-2). Does that make a difference or would I continue to do what you said. Oh actually now that I think about it, I completely messed up on a few things.
Homework Statement
My friend and I were having trouble with an equation, but I don't have the exact one with me so I will write one that is similar and is the same concept:
Equation: x^4 + 2x^3 - 9x^2 - ax + b
So basically they want you to find the two missing variables in the 4th degree...
Homework Statement

18x^2 + 3x -1 = 0
Homework Equations
The Attempt at a Solution
There are 2 complex roots.
Okay. So I cant factor anything out of the equation and when you try to factor it...
[SOLVED] Compex roots
Homework Statement
state the number of complex roots of each equation, then find the roots and graph the related function.
x^2 + 25 = 0
Homework Equations
The Attempt at a Solution
x^2 + 25 = 0
so there are 2 complex roots. Once I have established that...
ok thanks a lot. that really does help a lot. My tutor also pointed out some of my mistakes, but with the combination of that and this I'm very clear on the subject. thanks again

Homework Equations
The Attempt at a Solution
I am so lost here. I have no attempt. I am not asking you for the answer (i cant get answer without making an attempt which I don't have) i just need help. Please.
Homework Statement
Solve the equation:
2^x multiplied by 4^(x + 5) = 4^(2x - 1)
Homework Equations
The Attempt at a Solution
2^x multiplied by 2^2(x+5)=2^2(2x-1)
x(2x+10)=4x-2
2x^2+10x=4x-2
and that's as far as i could get before I was completely stuck. But this could be...

Also I forgot one of my personal favorites. Jimi hendrix. Not exactly metal but he is awesome. And I would have to say that the lead guitarists in Dream Theatre is one of the best, next to Herman Li from DragonForce
I'm interested in hearing what metal bands you guys like. I like death metal so my favorites are: Kataklysm, Amon Amarth, All that Remains, and Scar Symmetry. List your bands and some vids.
here are mine:

Homework Statement
Solve the equation:
(1/9)^m = 81^m + 4
Homework Equations
I know how to do a similar equation:
9^2p = 27^p-1
3^4p = 3^3p-1
cancel out the 3's because the base is the same.
4p = 3p-1
-3p -3p
1p = -1
The Attempt at a Solution
I know how to do ones...
why is one of the equations greater than or equal to zero and another is less then zero. I just don't understand why you would do this. Is there a lamens term explanation, haha or is it already in lamens terms?
