What is the distance between

(- 4, - 2, 12)

(- 4, 3, - 12)

https://socratic.org/questions/what-is-the-distance-between-4-2-12-and-4-3-12

601

Explanation: The Pythagorean Theorem gives the squared distance as the sum of squares of the difference of each coordinate:

d^{2} = (- 4 - - 4)^{2} + (- 2 - 3)^{2} + (12 - - 12)^{2}

Express the rectangular coordinate

(- 3, 4, - 12)

into spherical coordinates of form

(ρ, θ, ϕ)

tan θ + tan ϕ

https://math.stackexchange.com/questions/2057970/express-the-rectangular-coordinate-3-4-12-into-spherical-coordinates-of-fo

r = 9 + 16 = 5

tan θ = \frac{4}{- 3} = - \frac{4}{3}

ρ = 25 + 144 = 13

cos ϕ = \frac{- 1 2}{1 3}

tan ϕ = \frac{5}{- 1 2} = - \frac{5}{1 2}

tan θ + tan ϕ = - \frac{4}{3} - \frac{5}{1 2} = - \frac{7}{4}

Distance and displacement of an object on a straight line [closed]

https://physics.stackexchange.com/questions/36361/distance-and-displacement-of-an-object-on-a-straight-line

Suppose that the object was traveling on x-axis, hence we have following

(@ t = 0, x = - 4); (@ t = 4, x = 6); (@ t = 8, x = 6 - 8 = - 2)

a) ∣ (6 - (- 4)) ∣ + ∣ (- 2 - 6) ∣ = 18 .

b) - 2 - (- 4) = 2 .
