The tempereture outside where I'm at is [math]6.7 \ensuremath{^\circ}C[/math] ([math]44 \ensuremath{^\circ} F[/math], [math]279.8 \ensuremath{^\circ} K[/math]). So when I blow outside, the [math]CO_2[/math] from my lungs becomes visible. Why does this hapen?

Oh.

So, what does [math]\pi[/math] have to do with it? I understand what you guys were saying before, but I just don't understand what [math]\pi[/math] has to do with radians.

So, what exactly is a radian? And how do they help us?

I just learned how to do those' date=' there really fun. Try visiting the Latex tutorial.

So, how is [math]\pi[/math] used in trigonometry?

No' date=' here's what my algebra book says: down to another section of the book [math]\pi r^2[/math] is the measurment of the area. And why isn't my italic working properly?

It worked.

Okay.

You know, physics is my area of study, that's what I'm best at, so, I still insist on learning them.

It still didn't recognize it.

But what does [math]e[/math] equal? I think (I don't know if I'm correct, that's why I'm asking) [math]e[/math] is aproximatly equal to [math]2.17[/math]. Is that right. And does anybody know how to do aproximatly in [math]$L^AT^EX$[/math]?

Well, yes, I knew that [math]\pi[/math] was used for that, but I didn't exactly understand how it's used. I've done a thread on [math]\sin[/math] and [math]\cos[/math], and noticed that [math]\pi[/math] was used there a few times, but I didn't understand it (it would also help if Irken_Link would give me back my calculator [laugh]). That's why I did put [math]\pi[/math] up there with [math]e[/math], [math]y[/math], and [math]\phi[/math], because all I know about [math]\pi[/math] is that it helps in the circunfrence and area of a circle.

Could somebody explain to me begining calculus, such as calc 101. I'd like to know things like the difference between differential and intregal calculus, and how to use them.

I'm using Internet Explorer right now. It says:

Do you remember what thread it was, maybee I can look it up?

Thank you.

Sorry Bloodhound, but I didn't exactly understand what you were saying. Could you explain that in simpler terms.

I have already made a post for this, but that was in early October, and would be hard to find in all of the more recent posts. I wanted to know what the uses of the mathematical constants [math]\pi[/math], [math]e[/math], [math]y[/math], and [math]\phi[/math] are for, and what there uses are. For example, I know that [math]C=\pi r2[/math], and that [math]A= \pi r^2[/math], and that [math]\pi[/math] is aproximatly equal to [math]3.1415[/math]. So, I guess I understand [math]\pi[/math] pretty well. But I have no idea about [math]y[/math] [math]e[/math] or [math]\phi[/math].

And what about aproximatly? How do you put that symbol in?

Exactly what you sayed. If I understand correctly, you said not to type in C:\>, right?

What are complex numbers? I think I read somewhere that they where the same thing as imaginary numbers. Either the book was wrong (not likely) or I misread it? And why do you have to have both a positive and negative integer when it comes to multiplying the negative integers. Why does [math]-5^2=25[/math], and [math]i[/math] [math]\sqrt{-1}[/math]?

How would I write out something like [math]\sqrt{25} = 5[/math]? How would I put the [math]5[/math] above the [math]\sqrt{25}[/math]?
