1. ### Positron and anti-proton existence

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...
2. ### Simplifying with Pythagorean identites.

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...
3. ### Linear inequalities

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...
4. ### Not Sure to be honest

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...
5. ### Not Sure to be honest

yes, but that means you can plug in any two sets of numbers that work and they they ARE equal to those varibles when they really arent.
6. ### Not Sure to be honest

can you please explain in to further depth in such a way that I will understand? Please.
7. ### Not Sure to be honest

ok now its ok to re-read. Sorry for any inconvenience.
8. ### Not Sure to be honest

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.
9. ### Not Sure to be honest

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...
10. ### Another Complex root problem

oh sorry. In my book that section says "complex roots" but next time I will try my best to label it appropriately.

thanks.
12. ### Another Complex root problem

Homework Statement State the number of complex roots and then identify what the roots are. Equation: 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...
13. ### Compex roots

[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...
14. ### Complex roots

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
15. ### Complex roots

Homework Statement 6x^3 - 3x^2 - 45x Homework Equations The Attempt at a Solution -first factor out 3x 3x(2x^2 - x -15) 2 x 5 = 30 so... 3x(2x^2 + 5x - 6x - 15) -separate the equations 3x(2x^2 + 5x)( - 6x -15) -simplify a few things. 3x^2(2x + 5) -3 (2x + 5)...
16. ### Composite functions

I'm sorry but I'm really confused. I don't know what to do. I dont know what you want me to do with the "h's" and re-naming the problems
17. ### Composite functions

honestly i get what you just showed and explained to me but am clueless to what to do next? any hints please.
18. ### Composite functions

Homework Statement Given f(x) = 3/x-7 and g(x) = x^2 + 5x find each funstion below (f/g) (x) Homework Equations The Attempt at a Solution Okay so I think I have most of these steps but I think the only thing I'm missing is the factoring, which i sorta forgot over the summer. take it easy...
19. ### Trigomometric functions

so 240 is 60 degrees more than the 180 line of quadrant 2 so sin 60 = √3/2. is that right or am i totally off?
20. ### Trigomometric functions

Homework Statement Find the exact value of each trig function: Sin 240º 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.
21. ### Log equations

well in that case im really sorry! But its not like i meant it in a hatefl way. Sorry once again.:frown:
22. ### Log equations

Learn the basics yourself, you got it wrong!!!!!! jk
23. ### Log equations AGAIN!

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...

WOW! I actually understand that! thank you so much GIB Z and thank you Mindscrape. You guys rock!
30. ### Calculus functions

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?
