Tus qauv rau curvature yog dab tsi?
Yog qhov nkhaus yog lub vojvoog nrog lub vojvoog R, i.e. x=R nqi, y=R sin t, ces k=1/R, i.e., tus (tsis tu ncua) reciprocal ntawm lub vojvoog. Hauv qhov no, qhov curvature yog qhov zoo vim tias qhov tangent mus rau qhov nkhaus yog rotating nyob rau hauv ib tug counterclockwise kev taw qhia.
Koj pom qhov curvature ntawm parabola li cas?
- Curvature. Curvature yog ib qho kev ntsuas sai npaum li cas ib txoj kab tangent tig raws li qhov chaw sib cuag txav raws qhov nkhaus. Piv txwv li, xav txog ib qho yooj yim parabola, nrog qhov sib npaug y=x2. …
- Curvature rau parametrically txhais nkhaus. Ib qho kev qhia rau curvature kuj muaj yog tias qhov nkhaus tau piav qhia parametrically: x=g(t)
Dab tsi yog lub vojvoog ntawm curvature?
Nyob rau hauv qhov sib txawv geometry, lub vojvoog ntawm curvature, R, yog qhov sib npaug ntawm qhov curvature. Rau qhov nkhaus, nws sib npaug ntawm lub vojvoog ntawm lub voj voos uas zoo tshaj plaws kwv yees qhov nkhaus ntawm qhov taw tes. Rau qhov chaw, lub vojvoog ntawm curvature yog lub vojvoog ntawm lub voj voog uas zoo tshaj plaws haum rau ib feem lossis kev sib txuasntawm no.
Dab tsi yog curvature ntawm kev ua haujlwm?
Intuitively, qhov curvature yog tus nqi uas qhov nkhaus deviates los ntawm txoj kab ncaj nraim, los yog ib qho deviates los ntawm kev ua dav hlau. Rau curvature, tus piv txwv canonical yog lub voj voog, uas muaj qhov curvature sib npaug rau qhov sib npaug ntawm nws lub vojvoog. Cov voj voog me me khoov ntau dua, thiab yog li muaj qhov nkhaus siab dua.
