Re: re Activity: A Walk in the Desert (1 and 2)

hi

My computer will be out of action until (-6,7) (8,-8) (8,7) (-2,-2) (0,1) (-12,13) so I've put a shot of my spreadsheet down below so you can check your values.

If you can't wait until then and you need someone else to look at your work, I suggest you start a new thread because the others who watch this forum probably think I've got this thread covered.

Re: re Activity: A Walk in the Desert (1 and 2)

hi Bob
well, it is "tomorrow" 02:40 Thursday
i woke around an hour ago and thought i saw a fair amount of light -
which led me to "being with Jade" and with the aid of a circle with 15 degree divisions i deduced approximate bearings from all points.
my next step is to calculate them all again and compare my calculations with my "deductions"
the only points - bearings which are in doubt now - i think - are for points G, H and J
so i will do this first (after breakfast)
after that i will want to calculate all of the others for my own peace of mind.
watch this space .................
regards thanks etc
David

Re: re Activity: A Walk in the Desert (1 and 2)

hi Bob
I reckon i have it about 98% now
just a little confusion arising out of the difference in approach between the activity text and the way/s in which you dealt with the various aspects.

Many thanks for your patient help...........
best wishes

Re: re Activity: A Walk in the Desert (1 and 2)

hi diamond777,

I'm back on-line now. 

How's it going?  Have you got a set of results that you are happy with?

There's an interesting effect going on here that becomes apparent as you get lots of points.

Post back and I'll tell you about it.

Bob
