I need the answer as soon as possible

Transcribed Image Text:Ex2 :- given P(6,125°,-3), Q(3,-1,4) find the distance from :a- P to the
origin b-Q perpendicular to the z-axis c- P to the Q
Solution:-
• Q(3, -1, 4)
(0, 0, 4)
P (6, 125
a- P(p, Ø, z)
X-pcosø = 6cos125 = -3.44
y=psinø = 6sin125 = 4.915 ale
z=-3
V(-3.44)2 + (4.915)? + (3)² = v11.84 + 24.15 + 9 = 6.71
b- p = x2 + y2 = 9+1= 3.16
c- FPQ = (3 +3.44)āx + (-1– 4.915)āy + (4 + 3)āz
=6.44āx – 5.915āy + 7āz
: rPQ = V41.47 + 34.98 + 49 = 11.2
I did not understand
the point (b) why he
extracted (p)which is
mentioned in the
question the point
perpendicular to the
z axis
