PLE 2 The point (0, 5 3 , −5) is given in rectangular coordinates. Find spherical coordinates for this point. SOLUTION From the distance formula we have ρ = x2 + y2 + z2 = 0 + 75 + 25 = 10 Correct: Your answer is correct. and so these equations give the following. cos(φ) = z ρ = -1/2 Correct: Your answer is correct. φ = $$ Incorrect: Your answer is incorrect. cos(θ) = x ρ sin(φ) = θ = (Note that θ ≠ 3π 2 because y = 5 2 > 0.) Therefore spherical coordinates of the given point are (ρ, θ, φ) = PLE 2 The point (0, 5 3 , −5) is given in rectangular coordinates. Find spherical coordinates for this point.
