Day 67
An undefined slope
June 1st, 2010
I'm walking across America.
That's the idea, at least. I'm walking westward from New York City for nine months or so. If everything goes according to plan, I'll be in Oregon when the clock runs out. If nothing goes according to plan, maybe I'll end up in Peru or Mongolia or Pennsylvania. You can read all about the details of my trip if you're so inclined.

Here's my progress so far:
I think that one means “You don’t even want to know how steep!!!!”
Maybe it just means that the world is a little crooked and the truck is level…
Boy, those DOT guys sure do have a sense of humor!
Undefined? Could it be a divide by zero error? If grade percentage is vertical distances divided by horizontal distance, the grade is only undefined if the horizontal distance is zero… which is the case for cliffs, ledges, and other discontinuities.
It may be safer to take an alternate route – at least something where the grade is numerically tractable.
Gotta love the road signs. I’m thinking that someone simply forgot to print/paint in the appropriate number, as the % is off to the right.

Nah… it means your percentages of making it ain’t good in a big truck going down that steep hill!
wahaha
Who put the sign post in backwards ?
The guy who was promoted to measure the grade of the slope and paint it on the sign, of course! My guess it was Sven or Olie. If they had asked Lena to do it, Matt wouldn’t have had the opportunity to share his acute observational skills with us.
That’s one steeeeeep hill.
This will be on the trig final.
y = mx + b
