Perpendicular component of vectors

Click For Summary
SUMMARY

The discussion centers on finding the perpendicular component of vector p (i + j + k) relative to vector q (2i - j). Participants express confusion over the phrasing of the problem, specifically whether to calculate the component of vector p that is perpendicular to vector q or vice versa. Clarification is needed on the terminology used in the homework statement to accurately solve the problem.

Homework Statement



Vector p = i + j + k
Vector q = 2i - j

Find the perpendicular component of vector p of vector q.


I think i have provided everything what is required, i just don't know what to find. I didn't get what the perpendicular compnent of vector p of vector q means.

Thank you.

The wording is not at all clear.

Are you to find the component of vector p which is perpendicular to vector q ?

or

Are you to find the component of vector q which is perpendicular to vector p ?
 
Thats the thing, if it was any of those two you mentioned, i would've done it but our teacher stated the problem exactly as i have written it.
