Write the equation of the straight line through the point `(alpha,beta,gamma)`and parallel to z-axis. |
|
Answer» Direction ratios of the line parallel to `z`-axis will be `(0,0,1)`. So, equation of the line through the point `(alpha,beta,gamma)` and parallel to `z`-axis will be, `(x-alpha)/0 = (y-beta)/0 = (z-gamma)/1`. |
