Txhua lub ellipse muaj ob axes ntawm symmetry. … Txhua qhov kawg ntawm qhov loj axis yog lub vertex ntawm lub ellipse (plural: vertices), thiab txhua qhov kawg ntawm cov me axis yog ib qho co-vertex ntawm lub ellipse. Qhov nruab nrab ntawm lub ellipse yog qhov nruab nrab ntawm ob qho tib si loj thiab me axes. Cov axes yog perpendicular ntawm qhov chaw.
Yuav ua li cas koj thiaj nrhiav tau cov vertices ntawm ib tug ellipse?
Vertical Ellipse
Yuav kom pom cov vertices nyob rau hauv kab rov tav ellipse, siv (h ± a, v); txhawm rau nrhiav kev sib koom ua ke, siv (h, v ± b). Vertical ellipse muaj vertices ntawm (h, v ± a) thiab co-vertices ntawm (h ± b, v).
Yuav muaj pes tsawg lub vertices nyob rau hauv ib lub ellipse?
Txoj kab hla ntawm lub foci cuam tshuam cov ellipse ntawm ob lub ntsiab lus, qhov vertices. Cov kab ntu txuas nrog cov vertices yog qhov loj axis, thiab nws qhov nruab nrab yog qhov nruab nrab ntawm lub ellipse. Txoj kab perpendicular mus rau qhov loj axis ntawm qhov chaw sib tshuam cov ellipse ntawm ob lub ntsiab lus hu ua co-vertices (0, ± b).
Koj pom cov vertices li cas?
Kom nrhiav qhov vertex (h, k), get h(x-coordinate of the vertex)=-b/2a los ntawm tus qauv equation y=ax2+ bx + c thiab mam li nrhiav y ntawm h kom tau k (y-coordinate ntawm lub vertex).
Dab tsi yog vertex formula?
Lub vertex ntawm parabola yog qhov chaw uas parabola hla nws axis ntawm symmetry. … Hauv kab zauv no, lub vertex ntawm parabola yog qhov point (h, k). Koj tuaj yeem pom tias qhov no cuam tshuam li cas rau tus qauv sib npaug los ntawm kev muab faib tawm: y=a(x−h)(x−h)+ky=ax2−2ahx+ah2+k.
