With the 14-150 it becomes the all-rounder camera for light bike rides, with the pair PRO 12-40 f/2.8 and PRO 40-150 F/2.8 does not regret the older sisters EM-1 II or III. The sensor, in fact, is the same 20 Mpx, one of the best for the MFT format. The autofocus is ...

Olympus E-M5 III vs. Olympus OM-D E-M1 II vs. Olympus OM-D E-M5 II – Take a look at the quick comparison between all three major cameras. We have included the predecessor and company’s flagship Olympus E-M1 Mark II camera. ...
使得△DME的周长最小,即当x= =1时,L有最大值 =10, ∴A(x,-x 2 +4x),A的坐标为(1,3),连接OD与抛物线的对称轴直线x=2交于一点, 即AB=3,OB=1,CD=3,CM=1, ∴OF=2,OC=3,CD=3,PF∥CD, ∴EF=2, ∵A,D关于x=2对称,O,M也是关于x=2对称,则AC一定经过点E. ∴△DME的周长=EM+DM...
【详解】 (1)解: ∵∠AOB-90° .A、 O、 B都在OM上, AB是O M的直径, ∵A(4,0) ,B(0.3). ∴OA=4 , OB -3, ∴AB=√(OA^2+OB^2)=5 , M的半径为 5/2 : (2)证明:如图所示,设MC与OA交于E,连接BC, 点C为劣弧AO的中点, ∴MC⊥OH . ∴OE-AE-2 , ∴EM=√(AM^2-AE^2...
解答解:(1)∵直线AB与x轴交于点A(-6,0),与y轴交于B(0,6). ∴OA=6,OB=6, ∴S△ABO=1212OA•OB=1212×6×6=18; (2)如图1, 过点E作EM⊥x轴于M, ∴∠MDE+∠DEM=90°, ∵△BDE是等腰直角三角形, ∴DE=DB,∠BDE=90°, ∴∠MDE+∠BDO=90°, ...
∵D点在x轴负半轴, ∴D点坐标为(,0) (3)OG+OM=CM,证明如下: 设OM=m,则M点坐标为(0,m) 由(1)可知OA=OC=a,A点坐标为(-a,0),C点坐标为(0,a) ∴AC直线解析式为: AM直线解析式为: 如图,延长EM,AO交于点H, ∵∠CME=∠OMA,∠CME=∠OMH ∴∠OMA=∠OMH 又∵MO⊥AH ∴OA=OH=a ∴直线...
