Homework Answers
a)
Option A is correct.
The origin is fixed for polar as well as rectangular coordinates.
B)
Option C is correct .
Given, r = q^2 .
And q = 2t .
q'' = 0 , and t = 2 , q= 4 and r = 4^2 = 16 .
Therefore, option C is correct.
C)
Option A and D , ( Both are correct)
Cylindrical or polar coordinates are a suitable choice for the analysis of a problem forwhich data regarding the angular motion of the radial line r are given or cases where the path can be conveniently expressed in terms of polar coordinates.
If any doubt kindly comment. Thank you.

Polar coordinates are used for planes. Extending this system into three dimensions in the simplest way results in a cylindrical coordinate system. A cylindrical coordinate system uses the same r and θ as in polar coordinates, with an added dimension along to the z-axis. The three coordinates that define a point in a cylindrical coordinate system is the triple (r, θ, z). Consider a point in the three-dimensional Cartesian coordinate system, (3, −4, 6) cm. Dacia and Katarina compute the...
