1. The problem statement, all variables and given/known data Find the parametric and symmetric equations for the line through the point (2,1,0) and perpendicular to both <1,1,0> and <0,1,1,> 2. Relevant equations Parametric equ: x = x_0 + at y = y_0 + bt z = z_0 + ct 3. The attempt at a solution Cross product of <1,1,0> and <0,1,1> = <1,-1,1> = <a,b,c> Parametric equation: x = 2 + t y = 1 - t z = t Symmetric equation: x-2 = y-1 = z I'm not sure if I did this correctly. Is the cross product of the two vectors <a,b,c>?
