Find the rectangular coordinates of the point, whose cylindrical coordinates are given.

Question

(a)
(4, π/4, 1)
(x, y, z) =

(b)
(6, −π/3, 5)
(x, y, z) =

Answer 1

this is just polar coordinates with a z.

x = r cosθ
y = r sinθ
z = z

don't forget your algebra II now that you're taking calculus.
