| Aug 26, 2014 at 10:49 | comment | added | hassan | i am still waiting for a final comrehensive answer from seniors :)the formula also suitable in excel for my project. | |
| Aug 26, 2014 at 10:46 | comment | added | Claude Leibovici | @hassan. Sorry, I did not know there was any $z$ ! So, I am not only old but also stupid ! I apologize for that. Cheers. | |
| Aug 26, 2014 at 10:37 | comment | added | hassan | ok let me be more clear to my question. I have a cross section line AB with length of 2800m. The start point A(x1,y1,z1) is known.z1 is the bed elevation on point A. I need to calculate the coordinates at end point B(x2,y2). Now there are two situations. Case1: i have z2 at point B with me also. Case 2: i dont have z2 on point B with me. I need a formula suitbale for the solution of this problem. please help. | |

| Aug 26, 2014 at 10:11 | comment | added | Vikram | @ClaudeLeibovici, B can be at any elevation , if A is origin then B can be any one of the points on the circle with center at origin, you travel the given distance, but in which direction? | |
| Aug 26, 2014 at 10:09 | comment | added | Claude Leibovici | @MonK. Read the post again. The OP says that point $A(x_1,x_2)$ is known and that point $B(x_2,y_2)$ is unknown but the distance is known. I assumed no typo in the question. Cheers :-) | |
| Aug 26, 2014 at 10:06 | comment | added | MonK | Both $x_2,y_2$ are not known, infact the slope is unknown. | |
| Aug 26, 2014 at 10:05 | comment | added | Claude Leibovici | @Vikram.As far as I understood, only $y_2$ is unknown. | |
| Aug 26, 2014 at 10:03 | comment | added | Vikram | 1 eqn, 2 unknowns, how? | |
