What is the only trig expression Jesus mentions in the Bible?
Hint: tan(x)csc(x)
Answer: "secant ye shall find" to be the only reference
Proof:
1) Let x=unknown
2) Let unknown=doubt
3) Let Jesus eliminate any sin(doubt)

A woman asked her Mathematical boyfriend: "How do I look tonight, dear?"

He replies [math]\frac{tan(c)}{sin(c)}[/math]

She says "What?"

[math]\frac{tan(c)}{sin(c)} = \frac{\frac{sin(c)}{cos(c)}}{sin(c)}[/math]

[math]= \frac{1}{cos(c)} = sec(c)[/math]

I'll have to try that one out. My typical goal when looking for a date is to find someone who knows how to use the word "orthogonal" in casual conversation. Perhaps this method will work better.

When someone says "I love you infinity plus one", I immediately love them less because of their failure to grasp basic mathematical concepts.

Don't be so quick. If $\omega$ is the order-type of natural numbers, then $\omega+1$ is a well-defined concept. See ordinal arithmetic.

Speaking of infinite sets, there is a mathematical variant of the song "99 Bottles of Beer". I encountered an opinion that "Aleph-Naught bottles of beer on the wall" is the longest song ever. I am not sure about aleph-naught, denoted by $\aleph_0$, which is the cardinality of natural numbers, but if it is replaced by $\omega$, then the song is definitely finite since $\omega$ is well-founded, i.e., there is no infinite chain $\omega>n_1>n_2>\dots$.

Hello again gentlemen, I hope you enjoyed the (relatively short) time you've spent on MHB without me. Thus I inform, with regret, that you all are, once again, going to see the dark days of MHB now that I've returned. To celebrate this historical moment, I am going to start with a joke I've heard in recent times of my imprisonment in the dungeons of the Necromancer.

At least it is still about reals. Otherwise it would become... complex.

It took me a bit of time before I realized they misspelled Itu.
So yeah, it doesn't make sense.

Wait, I don't get it. Is that referring to "e to the (power of) i pi"? I can't make sense of won snot.

It is deliberately misspelling/slangifying "e to the (power of) i pi and one is not(hing)".

Symbolic manipulation becomes easier after so much practice. Can you do $19,245 \times 52,091$ faster than $$\int \sec^2 (x) \, dx?$$

no. i can do it fast but definitely not as fast as integrating sec^2x

Code:

----------
     19245
   173205
   00000
  38490
 96225
----------

Almost ;)

I subscribe to Einstein's point of view: you don't need to know everything, just that it exists and where/how to find it. In any case, it wasn't a fair comparison: $\tan(x)$ has a simple derivative that can easily be memorized, whereas $19245 \times 52091$ is rather arbitrary.

But this would be a rounding error.

Why do you so seldom see mathematicians at the beach?

Because they use the sin, and not the sun, to get their tan.

A chemistry joke, or the Need to state your wishes precisely

A genius high school chemistry student takes a test, gets his score back, and is dismayed to find that he missed exactly one question and thus would not be accepted to his university of choice. He is especially bummed because the question he missed was "how many valence electrons does a hydrogen atom have?" In his haste to complete the test, he had answered 2.

Depressed and despairing, he takes a walk alone along a beach, and is lost in thought when he trips on a metal object in the sand. Picking it up, he finds it to be a brass oil lamp, and as his fingers brush the surface a genie suddenly appears! The genie thunders, "I can grant you anyone wish, but you must answer now. What do you desire?" The student immediately replies, "I wish I had gotten that question right," and the universe explodes.

Some student answers during exams.

  • The expression $\pi=\frac{C}{d}$ means that $\pi$ is directly proportional to the circumference and inversely proportional to the diameter.
  • The number of elements on the main diagonal of a square matrix of size $n$ is $n\sqrt{2}$.
  • A function is continuous if there exists every epsilon…

As a preamble to the following story I'd like to remind you about the role the year 1917 played in the history of Russia. That year two revolutions happened in Russia: the first resulted in the abdication of the tsar, and the second brought the Bolshevik rule and led to the appearance of the Soviet Union. The anniversaries of the October revolution (even though it happened in November according to the Gregorian calendar) were one of three or four major holidays in the Soviet Union.

The story was told by Vladimir Tikhomirov, a mathematician working in the area of functional analysis and mathematical optimization, a distinguished professor of Moscow State University. It's about Dmitri Menshov, one of the first Soviet mathematicians.

Once in the 1960s there was a meeting between students and faculty of the department of functional analysis. Menshov was asked to speak about the origin of the Moscow mathematical school. This is what he said.

"In 1914 I was admitted to Moscow University. Prof. Nikolai Luzin then lived abroad, but he arranged with Prof. Dmitri Egorov that they would organize a research seminar for students. And Prof. Egorov did start this seminar in 1914. It was devoted to numerical series. The following year Prof. Lusin returned to Moscow and started to supervise the seminar himself. In 1915 we studied functional series, and in 1916, orthogonal series.

And then came 1917. It was a very memorable year of our lives. That year happened an event that influenced our entire life: we started studying trigonometric series…"

Evaluate this expression: $7(3^2-5)-7+3$. You may be surprised to discover that the result is 4!
