1.	Find the distance of the point `veca` from the plane `vecr*hatn=d` measured parallel to the line `vecr=vecb+vec(tc)`.
Answer» A line parallel to `vecc` and passing through `A(veca)` is `vecr=veca+lamdavecc` A point for some `lamda` satisfies plane `" "(veca+lamdavecc)hatn=d` or `" "lamda=(vecd-vecahatn)/(vecchatn)` `therefore" "` Distance `= (\|vecd-hatahatn\|)/(\|vecc*hatn\|)\|vecc\|`.
