### Instruction: help me answer this question Find the coordinates of the foci, vertices, length of major axis, length of minor axis, eccentricity, and length of latus rectum for the equation 16x^2 + y^2 = 16., think step by step
### Assistant:  , The answer is {'foci': ['(0, √15)', '(0, -√15)'], 'vertices': ['(0, 4)', '(0, -4)'], 'major axis length': 8, 'minor axis length': 2, 'eccentricity': '√15/4', 'latus rectum length': '½'}
