The discussion centers on determining the direction of the x-axis using the Right Hand Rule in a three-dimensional coordinate system. Given that z represents east and y represents south, the correct answer for x is up. The Right Hand Rule dictates that when the fingers point from y to z, the thumb points in the direction of x, confirming that x is indeed up.
PREREQUISITESThis discussion is beneficial for students studying physics, particularly those focusing on mechanics and vector analysis, as well as educators teaching coordinate systems and vector mathematics.
jedishrfu said:that can't be right because y is already south
you know z=east so that -z=west and y=south so that -y=north so what else is left for x?
Yes. Rotating y into z gives x for your thumb.Tiven white said:really sorry i meant up is that correct?
