As a math teacher and math lover, things like this make me sad and mad. It seems the purpose of this clock is to force the reader to perform a mathematical calculation.
Oh, except for eleven. I guess they couldn’t think of a mathematical expression for eleven. Let’s just write that out as a word. That’s equally as difficult.
Actually, I guess they really ran out of ideas because they used the radical of a perfect square twice: once for two and again for eight. Two cubed maybe?
Nine is not equal to three times the quantity of pi minus 0.14. That expression is only approximately nine because pi is not equal to 3.14. Rookie mistake.
52 minus x squared plus x equals ten has two solutions: negative six and seven. Oh, it’s 7 o’clock or -6 o’clock. Or maybe we can pretend it’s prior to the 1600’s when negative roots for quadratics were rejected as answers. But wait, it’s 2012.
Lastly, Tan(45) is equal to about 1.6198. Oh, I thought it was one. Well, the Tan(45 deg) is equal to one, but if units are not specified the units are understood to be radians. Advanced rookie mistake.
Come correct or don’t come at all. Props for the gamma and integral hands.
Real Life Math: When to have tutoring?
I had my students tell me when they had free periods so I can schedule tutoring in such a way to help as many of them as possible. I have 137 students. 85 of them have H band free, 105 have E band free, and 67 have H band and E band free. How many of my students are not free either E band or H Band? HINT: Use a Venn Diagram.
The Complexities of Imaginary Numbers
Last month was Math Awareness Month and also National Poetry Month. Being a lover of both, one of the Problem of the Week’s in my classroom was to write a mathematical poem. I use to write a lot of poetry, but find it hard to fit it into my schedule as of late. It took me about two weeks to write the piece below. It’s about imaginary numbers. It’s packed with mathematical imagery. Enjoy.
Her i’s are imaginary,
yet i can see them in my dreams.
On complex planes, reality
makes right angles with the unseen.
Her i’s are simple yet complex
conjugates of pure perception…
the place where our souls intersect
with unimagined perfection.
Her i’s cannot be simplified
or combined with the likes of mine.
So the world left her to abide
alone in blight, yet they are blind.
I see her negativity.
Deep down, she’s just a lonely one
with radical proclivities,
caged by her own disposition
Fear not for I see with real eyes
what most the world never realize.
With the power of you and I
placed aptly atop your left side,
