Hey TSny!
Thank you it was a sign error!
xi = -61.07
yi = -45.80
Range = sqrt[ (-61.07)^2 + (-45.80)^2 ] = sqrt(5827.17) = 76.33. close enough
Thank you both for all your help. I was really confused.
Hi TSny, thanks for the quick reply.
- the 'd' in the cosd does denote that the argument is in degrees (from matlab, dunno why I included it here)
- the 'i' does mean intersection. apologies.
- I will look into the sign error, hopefully that fixes it.
Hi mfb, thank you for the quick response.
- Oh! Yes my my coordinate system is a right handed one: x positive right, y positive up
- Unfortunately, my final answer is different than the solution.
ANS: Range = 76.5 meters
Range = sqrt( xi^2 + yi^2) = sqrt( 17.126^2 + 12.8449^2) = 21.4 meters...
