"Things to Try on Math Tests" Chapter 1.
i once got my teacher to make a smiley substitution in class... also had a teacher who raised things to the flower power. was freakin awesome
This one goes up on the bulletin board with the classic Foxtrot physics test comic.
My calc II prof did that on several occasions when the majority of the class wasn't getting what was going on.. I remember it clearly, "the integral of the squiggle dx is squigglex +C!"
Shouldn't that have been (squiggle^n)/n-1?
integirl is correct if the squiggle was a constant and the integral was indefinite. The power rule is a more general form if the squiggle was a constant multiplied by a power of x, it would not hold if there was a trigonometric function involved. Also you are missing the most crucial part, + C.
oh i was wondering why he wanted revenge
I see--this one is the continuation of yesterday's looking for revenge. He he he! Talk about a perfectionist.
A math teacher I once knew said he was going through security 50 or so years back with a bunch of new pencils. The guard noticed them, pointed at the erasers, and said, "This is because nobody is perfect, huh?" and laughed when the teacher ruefully agreed.
I remember I needed to use a symbol on a mechanics problem set...so I ended up using d(triforce)/dt in a differential equation.
Lol. This reminds me of the time I wrote an entire calculus exam using roman numerals... from then on, the "read this before you start" paragraphs always included "write your numerical answers using arabic numerals" =P
Math n00b, he used the quadratic formula! Use the pq formula. (-p/2)+/- sqrt((p/2)^2 - q). So simple.
funny. engineers use squiggle all the time - its apparently either called xi or zeta.
A Norwegian friend of mine said she once had a teacher who had previously been a kindergarten teacher, and used pictures of giraffes and other animals as variables. Maybe she was related to Evan Wantland.
My Abstract algebra prof uses smiley faces all the time. He thinks it helps when talking about groups to show that it's not "just" multiplication as the operator. Yeah... we just all think it's funny. And props to "@bob the carrot" for the roman numerals.
And now Abstruse Goose has a comic on roughly the same theme: http://abstrusegoose.com/345
I made one
Correct me if I'm wrong... but shouldn't that be "squiggle^2 - 42 squiggle MINUS 360", not plus? Not at quadratics yet, so there may be a rule I'm unaware of, but felt I should point that out anyway.
It's correct. Re-calculate it carefully. :D
Regard the awkward symbols as x and y, and do the math on a piece of paper!
When he forms the quadratic, it should be - 360, not + 360.
