In summary: I think Pengwuino is busy eating avocado lasagna :tongue2:In summary, a teacher is grading their students' first lab assignment, which was a 175 question math review covering basic addition to logarithms and basic algebra. The first student did decently, but the second student's poor performance caused the teacher to cry. The teacher expresses frustration at the lack of arithmetic skills in their students and shares that they have considered switching to multiple choice exams. Other individuals join in the conversation, sharing their own struggles with teaching and students' lack of basic math skills. The conversation also briefly mentions a recipe for avocado lasagna.

If i is greater than or equal to one, then he's correct.

Could you clarify the value of i?

And what does h stand for? Hypotenuse? If this a trigonometric equation, then your student was obviously wrong.

But you're leaving me guessing as to the value of your variables.

[itex]i = \sqrt{-1}[/itex]

Well, what is the answer? Don't just leave it dangling like that in suspense!:confused:

WhoooahKay! Here's the correct answer:

The government of the National Socialist German Workers Party was dissolved by the Allied Powers on 23 May, 1945. Construction of the Berlin Wall (officially the "Anti-Fascist Protective Barrier") was begun by the government of the German Party of Socialist Unity of the German Democratic Republic on 13 August, 1961, for the purpose of preventing the escape of GDR citizens to the west. Publius Quinctillius Varus (not Varius, I got that one wrong!) led the XVII, XVIII, and XIX Legions into the forest of Teutoburg (literally, the "Earthworks of the People" (far preferable to the "Anti-Fascist Protective Barrier"), where my ancestors made mincemeat of them (more literally than most of you would care to think!) in 9AD.

Micromass and NeoDevlin:

OK, now you're violating the laws of mathematics.

How can any even-numbered exponential have a negative number as a product?

If this is, indeed, an "imaginary constant". then what's its purpose?

Trust me, there's no violation. Keep taking math and physics classes, and you'll know soon enough :wink:!

It's the definition of i. Basically, we adjoin a number i to [itex]\mathbb{R}[/itex] that has the property that [itex]i^2=-1[/itex]. Of course, i cannot be a real number, as the square of a real number cannot be negative. So i has to be another kind of number: a complex number.

The purpose of complex numbers was (originally) to being able to solve equations. It was nothing more than a handy tool in the beginning. But now complex numbers have even found their way into physics and electrical engineering.

Doesn't anybody want to take me up on my "Siphon Theory" challenge?

Like I said, I like winning online arguments, and I'm clearly losing this one!

Just kidding, I'm perfect. You should be ashamed.
