There are 2 types of gradientsDoes anyone know any trig tricks for gradients or azimuths.
Yes for Gradients, (Depending on what values are given e.g: straight line distance, land distance, hight difference)By trig I meant trigonometry, I assume the tan function could be useful
I total agree. This is div B events where most 6-9 graders HAVE NOT been exposed to trig yet. Keep in simple, just measure the distant and change in elevation, then multiply by either 100 or 1000 depending on whether it's road gradient or stream gradientTrig is a really useful thing to use. However, test-makers will be making the tests knowing that most competitors will probably not know trig. Also (for azimuths especially), using the conventional method likely leads to a fuller understanding of what you're actually calculating, so for anyone else who's reading this, I would recommend not trying to use a trig shortcut unless you're already very comfortable and familiar with the concepts behind it. Of course, it's possible there's an easier method to use trig than either of those I've put here, and as long as the method gets you the answer, there's no harm done. I just don't recommend this to other people who may not be as experienced in the event.
You can download topo maps here: http://nationalmap.gov/ustopo/index.html Printing them at a high enough resolution to be useful may or may not be possible at your school, but I imagine Kinko's or Staples etc could do it. If your team participates in any invitationals, it's possible that you'll be allowed to take the map home. I was lucky enough to grab a handful of different maps at a coaches' conference last year which my students use to generate their own questions for their partners to quiz on.How do other people do practice tests? I can't seem to find the maps.
