Two Liberal Dudes

We're two liberal dudes who talk about stuff that interests us, such as politics.

emeraldbeaches:

Are (x-3)^4/4 and 1/4*(x-3)^4 the same thing?

No, not in the way you wrote it. If you mean (x-3)^1=1/4(x-3)^4 that is not true. But if you wrote it as ((x-3)^4)/4=1/4(x-3)^4 then yes.

emeraldbeaches asked: What do you mean by "take the inverse sine of both sides to get the following x=arcsine(1), which implies x=pi/2"? What does arcsine mean?

Oh, the arcsine is just another word for the inverse sine function, or a function that takes in a value of sin(x) and gives out x. Also, I made a slight mistake. It is written arcsin(x) not arcsine(x).

someone explain this formula please?image

Perhaps I can help with an example. The expected value is a weighted average of events based on probability. Let’s let X be a coin flip, where x=1 is when the coin lands heads. E(X)=1*Prob(heads)+0*prob(tails)=1/2

or let X be a six sided die, with X=the outcome. Then the expected value is the sum of each of the values multiplied by 1/6, doing the calculation, you get E(X)=3.5.

darkeningofheart: I got to this point, idk what to do after this You can’t solve it like a polynomial. The second step is correct, then divide both sides by 2cos(x) to get 1=sin(x). Take the inverse sine of both sides to get the following x=arcsine(1), which implies x=pi/2

darkeningofheart: If someone is willing to help….please Using the double angle identity, you get 1=sin(x). Using arcsine(1)=pi/2, that implies x=pi/2. given the domain of x.

Watch as I enter my bid to be Jimmy McMillan’s strategist (The Rent is too Damn High dude)

Essentially CISPA allows private businesses to share private information with each other, and the government anonymously, and without legal repercussions. That sounds disastrous, doesn’t it?
