Hello, I'm stuck in an essay that I am writing about the Pythagorean theorem and the Distance Formula.
I am directed to describe real world applications for the use of the distance formula in 2 and 3 d. I'm good on 2d, but struggling with 3 d.
I've gotten lots of ideas that use just the P theorem, (what i mean, is where you already know the length of two sides and want to find the diaganol, for example)... but none that fit the assignment which is:
"The distance formula needs to be applied to at least two real-life examples, which means coordinate axes need to be defined and coordinates need to be assigned to the points." (in 3d)
I appreciate any direction that can be provided.
