Descartes' formula disul-e Descartes Fr.: formule de Descartes A formula that gives the position of an image formed by highly
→ x = 2/_{i}x, where
_{C}x is the distance along the
→ _{o}principal axis
from the mirror to the
object, x is the distance from mirror to image, and
_{i}x is the distance from the mirror to its center of curvature.
Any distance measured on the same side of the mirror as the reflecting surface is
positive; on the other side, negative. Thus for a
→ _{C}concave mirror x
is positive; for a → _{C}convex mirror, negative. |

Euler's formula disul-e Euler Fr.: formule d'Euler A formula which expresses an → i sinθ, e = cos θ - ^{-iθ}i sinθ, cosθ = ( e + ^{iθ}e)/2, ^{-iθ}sinθ = ( e - ^{iθ}e)/2^{-iθ}i. In the particular case of θ = π, Euler's formula becomes: e^{iπ} + 1 = 0, which is considered by many mathematicians to be
the most elegant mathematical equation. → mathematical elegance. |
