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

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...
5. ### 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...
6. ### 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...
7. ### 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)...
8. ### 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...
9. ### 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.
10. ### 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...
