expression, noun
Archimedean spiral
A mathematical curve defined in polar coordinates by r = a + bθ. Used in geometry and engineering.
アルキメデスの螺線は、極座標で r = a + bθ と表される。
The Archimedean spiral is expressed in polar coordinates as r = a + bθ.
螺線 is the general term for 'spiral' or 'helix', while アルキメデスの螺線 specifically refers to the Archimedean spiral.
Named after the ancient Greek mathematician Archimedes, who studied this curve. The Japanese term is a direct translation of the English 'Archimedean spiral'.
