- 已知點(diǎn)C為線段AB的黃金分割點(diǎn)且AB=2，則AC≈_（精確到0.1）．
- 已知C為線段AB上一點(diǎn),AB=a,AC=b,且1/a+1/b-1/a-b=0,試說(shuō)明點(diǎn)C是線段AB的一個(gè)黃金分割點(diǎn)
- 已知點(diǎn)C是線段AB的黃金分割點(diǎn),且AB=1,求AC長(zhǎng)
- 點(diǎn)c是線段上的一個(gè)黃金分割點(diǎn),若AB=10則AC=有兩個(gè)答案要計(jì)算過(guò)程
- 如圖一,點(diǎn)C將線段AB分成兩部分,如果AC：AB=BC：AC那么稱(chēng)點(diǎn)C為線段AB的黃金分割點(diǎn)
