Math, eh?

See lots of math puzzles floating around. Just thought I'd throw something slightly different out there for fun and excitement.

List all possible solutions, x, where sin(x) = π

(π <-- That's a pi in my font, for those of you who can't see it clearly.)

I was trying to do all these calculations, until I realized what a noob I am.

The answer is undefined, because the maximum value of sin (x) is 1. pi = 3.1415926.

Got fooled when I saw pi, thinking that we were working in radians.

My turn for math questions

(This one took me 2 days... and I still couldn't figure it out until I gave up and asked my teacher how in the world do you solve this?!)

Given Log_a2 = x and (log_a

(a^log_ax) = 12
Solve for a.

First off, you guys are asking much more serious math problems, which defeats the point of the ones I have been putting up. Most people SHOULD have a grasp of the basics of math, but clearly do not, which is what I was pointing out with those problems I have been putting up. These however are more advanced, which the average person would have no way to know even where to begin. That said...

As ruisen has said, undefined. This isn't a puzzle, nor is it basic math.

Quoted from "ruisen2000;601131"

Given Log_a2 = x and (log_a(a^log_ax) = 12
Solve for a.

1.41421 or 99/70 or √2 ...also not a puzzle nor basic math.

Math questions: What place in this world can have its temperatures in Fahrenheit and Celsius equal?

You're assuming that A) I posted that question in "response" to your "basic" math questions, and B) that I did so with some malicious intent toward you. Neither of these cases are true.

Quoted from "ghostwolf82;601142"

This isn't a puzzle,...

All math is puzzles. I enjoy mathematics for this very reason: I approach each "problem" like a puzzle -- it's a game to me. Can I apply the correct logical principles and derive a correct answer? Answering that is why I love mathematics.

Sorry, I didn't see the part in the forum rules where any math questions that I posed had to be targeted to the masses.

umm, did you just ask what the derivative of a constant is?

oh shoot, i didnt come up with a fun math problem, I'll have to think of something...silly work getting in my way

I didn't think you had any malicious intent, but it was in response of sorts to my basic math questions, seeing as I was the only one posting anything about math in the last 4 years -_- soooo yeah. Anyways, you are right that you can aim your questions at anyone you want.

Also, nice one trying to trick us with the last one

so, zero because the slope of any given line is always zero.

I realized after I had reread what I'd posted that it might have sounded a little more harsh than I had intended, so I apologize if that were the case.

I wasn't considering the new post a "response" moreso than a "fork," I guess. Heh.

At any given rate, you and I seem to share the same view that there is a disturbing lack of mathematical aptitude in upcoming generations. I'm curious, however, to discuss what you think are the underlying reasons.

Antartica is the answer.

What is the opposite of 0?
Two men, standing back to back, begin to walk away from each other. One man's stride is twice the length of the other man's stride. After ten strides both men stop walking because they have arrived at the same spot. How is this possible? There are 2 answers.
If 5 + 3 = g and 1 + 3 = o, what does 1 + 7 equal? (Hint: wait until it stops raining to figure this out!)
