2.判斷一個(gè)三角形是否為等邊三角形的方法有:檢查三個(gè)角是否都是60°;檢查三條邊的長(zhǎng)度是否都相等;檢查是否有一個(gè)角是60°,且其他兩個(gè)角的和為120°。

4.數(shù)列是一系列按照一定順序排列的數(shù)。等差數(shù)列的特點(diǎn)是相鄰兩項(xiàng)之差相等,如1,4,7,10...;等比數(shù)列的特點(diǎn)是相鄰兩項(xiàng)之比相等,如1,2,4,8...。

5.利用對(duì)數(shù)函數(shù)的性質(zhì)解決實(shí)際問(wèn)題,如求兩個(gè)數(shù)的冪,比較大小等。例如,已知\(10^2=100\)和\(10^3=1000\),則\(10^{\log_{10}(1000)}=1000\)。

五、計(jì)算題

1.第10項(xiàng)為\(a_{10}=2\times10+1=21\)。

2.\(x=1\)或\(x=3\)。

3.函數(shù)的值為\(y=3\times1^2-2\times1+1=2\)。

4.點(diǎn)A和點(diǎn)B之間的距離為\(\sqrt{(5-2)^2+(1-3)^2}=\sqrt{9+4}=\sqrt{13}\)。

5.函數(shù)的導(dǎo)數(shù)為\(f'(x)=-\frac{1}{x^2}\),當(dāng)x=2時(shí),\(f'(2)=-\frac{1}{2^2}=-\frac{1}{4}\)。

六、案例分析題

1.剩下的5名學(xué)生的平均分?jǐn)?shù)為\(\frac{(30\times80-25\times85)}{5}=75\)分。

2.降價(jià)后的售價(jià)為\(150\times0.9=135\)元,銷量為\(40\times1.2=48\)件,平均利潤(rùn)為\((135-100)\times48=2160\)元。

知識(shí)點(diǎn)總結(jié):

1.函數(shù)與方程:包括函數(shù)的基本概念、性質(zhì)、圖像、一元二次方程的解法等。

2.三角形:包括三角形的性質(zhì)、角度、邊長(zhǎng)、面積、周長(zhǎng)等。

3.數(shù)列:包括數(shù)列的基本概念、等差數(shù)列、等比數(shù)列、數(shù)列的通項(xiàng)公式等。

4.應(yīng)用題:包括實(shí)際問(wèn)題中的數(shù)學(xué)建模、方程求解、幾何計(jì)算等。

題型知識(shí)點(diǎn)詳解及示例:

1.選擇題:考察學(xué)生對(duì)基本概念、性質(zhì)、公式等的掌握程度。
