And once you've worked out what CP^2 is in terms of a^2 b^2 and a dot b, then you can just let a and b be at right angles to each other, making a right angled triangle, and hence a dot b = 0, and you can show CP^2 = AP^2.

:. |CP| = |AP| as required for the last part of the question.

Well i think i got the first part to iii.

normal to plane = 2i -3j +k

vector parrallel to line = 3i-3j-4k

then use the cosine of an angle formula thing and you get 11/ root 476


then im stuck from here on.
