### Example Question #171 : 3 Dimensional Space

A point in space is located, in Cartesian coordinates, at . What is the position of this point in cylindrical coordinates?

**Possible Answers:**

**Correct answer:**

When given Cartesian coordinates of the form to cylindrical coordinates of the form , the first and third terms are the most straightforward.

Care should be taken, however, when calculating . The formula for it is as follows:

However, it is important to be mindful of the signs of both and , bearing in mind which quadrant the point lies; this will determine the value of :

It is something to bear in mind when making a calculation using a calculator; negative values by convention create a negative , while negative values lead to
