Nruab nrab ntawm ib kab Segment
- Ntxiv ob qho "x" coordinates, faib los ntawm 2.
- Ntxiv ob qho "y" coordinates, faib los ntawm 2.
Tsis tas li ntawd, koj yuav nrhiav tau qhov nruab nrab li cas?
Cov qhov nruab nrab yog lub ntsiab lus ntawm ntu ib nrab ntawm cov ntsiab lus kawg. Tej zaum yuav yog cov ntaub ntawv uas qhov nruab nrab ntawm ib ntu tuaj yeem pom yooj yim los ntawm kev suav. Yog hais tias ntu yog kab rov tav lossis ntsug, koj tuaj yeem nrhiav tau qhov nruab nrab los ntawm kev faib qhov ntev ntawm ntu los ntawm 2 thiab suav cov nqi ntawd los ntawm ib qho ntawm cov ntsiab lus kawg.
Ib tug kuj yuav nug, dab tsi yog txoj cai nruab nrab? Cov txoj cai midpoint . Qhov no txoj cai siv cov qhov nruab nrab ntawm txhua lub sijhawm raws li lub ntsiab lus ntawm qhov ntsuas qhov ua haujlwm rau Riemann sum. Yuav kwv yees, lub qhov nruab nrab formula nrog slivers ntawm vaj huam sib luag yog: Yog li ntawd txoj cai midpoint kwv yees thaj chaw raws li qhov sib npaug ntawm thaj chaw ntawm -tangent trapezoids.
Ua qhov no hauv kev xav, qhov twg yog qhov nruab nrab ntawm AB?
Teb: Point G yog qhov midpoint AB.
