Re: Newbee needs help

I will just say what I'm doing now and you can tell me if there is an
easier way than this.
First I start with the instrument setting at a "given" coordinate location
of 4000, 4000 so as to stay away from negative values.
Then I backsite a point and assign it a speculative Azimuth based on
relation to the sun. So we will say my backsite azimuth is 315 degrees.
Then I turn the instrument to the right an angle of 165 degrees and shoot
a distance of 100 feet. I add my backsite azimuth of 315 to the new front
site angle of 165 which = 480 degrees. Since this is more than 360degrees
I then subtract 360 from 480 giving me a new front site azimuth of 120
degrees.
I now take the (cos120degrees) 100feet = (-50)
So I add the instruments occupied y coord to (-50) and I get a y coord for
the
new front site point of 3950
I then take the (sin120degrees) 100feet =86
So I add the instruments occupied x coord to 86 and I get an x coord for the
new front site point of 4086.
Is there an easier way than this ?
