Wave your hands in the air like you 're a mathematician

In summary, a Twitter user shared a post on their Facebook wall about possible errors in a graph. One user pointed out that 1/x and -1/x may be incorrect, but could still work with some imagination. However, the graph for sinx should actually be -sinx. The hands for tan x and cot x also need to be adjusted to point up or down, instead of deflecting. Additionally, the graph for \log_a(x) is not accurate and the graph for y=a^x may be painful for anyone who is not a tentacle monster.

I posted this on our facebook wall awhile back and a few said there were errors. Can anyone find them?

It looks like 1/x and -1/x are incorrect, but if you use your imagination they work. I think the others are all good though.

edit: actually sinx is a graph of -sinx

The hands of tan x and cot x should be pointing up/down. Instead they look like they're deflecting (although the left hand of cot x looks OK).

[itex] \log_a(x) [/itex] is way off.

Needs to dislocate his shoulders more for [itex]y=a^x[/itex]. Some of those look quite painful for anyone who isn't some kind of tentacle monster.
 

1. What does it mean to "wave your hands in the air like you're a mathematician"?

Waving your hands in the air like a mathematician is a common gesture used to express excitement or understanding during a mathematical discussion or presentation.

2. Why do mathematicians wave their hands in the air?

Mathematicians often use hand gestures to help illustrate complex ideas or concepts during a presentation, and waving their hands in the air can add emphasis and energy to their explanations.

3. Is waving your hands in the air a necessary part of being a mathematician?

No, waving your hands in the air is not a necessary part of being a mathematician. Some mathematicians may use hand gestures while others may not, and it does not affect their ability to do mathematics.

4. Can anyone learn to "wave their hands in the air like a mathematician"?

Yes, anyone can learn to wave their hands in the air like a mathematician. It is simply a gesture that can be used to express excitement or understanding during mathematical discussions.

5. Is "waving your hands in the air like a mathematician" a universal gesture in the math community?

No, waving your hands in the air like a mathematician is not a universal gesture in the math community. It may be more common in certain cultures or among certain groups of mathematicians, but it is not a universal practice.
