  • 北師大初中九年級數(shù)學(xué)下冊圖形面積的最大值1教案

    北師大初中九年級數(shù)學(xué)下冊圖形面積的最大值1教案

    如圖所示,要用長20m的鐵欄桿,圍成一個一面靠墻的長方形花圃,怎么圍才能使圍成的花圃的面積最大?如果花圃垂直于墻的一邊長為xm,花圃的面積為ym2,那么y=x(20-2x).試問:x為何值時,才能使y的值最大?二、合作探究探究點一:二次函數(shù)y=ax2+bx+c的最值已知二次函數(shù)y=ax2+4x+a-1的最小值為2,則a的值為()A.3 B.-1 C.4 D.4或-1解析:∵二次函數(shù)y=ax2+4x+a-1有最小值2,∴a>0,y最小值=4ac-b24a=4a(a-1)-424a=2,整理,得a2-3a-4=0,解得a=-1或4.∵a>0,∴a=4.故選C.方法總結(jié):求二次函數(shù)的最大(小)值有三種方法,第一種是由圖象直接得出,第二種是配方法,第三種是公式法.變式訓(xùn)練:見《學(xué)練優(yōu)》本課時練習(xí)“課堂達標訓(xùn)練” 第1題探究點二:利用二次函數(shù)求圖形面積的最大值【類型一】 利用二次函數(shù)求矩形面積的最大值

  • 北師大初中九年級數(shù)學(xué)下冊圓內(nèi)接正多邊形教案

    北師大初中九年級數(shù)學(xué)下冊圓內(nèi)接正多邊形教案

    解析:正多邊形的邊心距、半徑、邊長的一半正好構(gòu)成直角三角形,根據(jù)勾股定理就可以求解.解:(1)設(shè)正三角形ABC的中心為O,BC切⊙O于點D,連接OB、OD,則OD⊥BC,BD=DC=a.則S圓環(huán)=π·OB2-π·OD2=πOB2-OD2=π·BD2=πa2;(2)只需測出弦BC(或AC,AB)的長;(3)結(jié)果一樣,即S圓環(huán)=πa2;(4)S圓環(huán)=πa2.方法總結(jié):正多邊形的計算,一般是過中心作邊的垂線,連接半徑,把內(nèi)切圓半徑、外接圓半徑、邊心距,中心角之間的計算轉(zhuǎn)化為解直角三角形.變式訓(xùn)練:見《學(xué)練優(yōu)》本課時練習(xí)“課后鞏固提升”第4題【類型四】 圓內(nèi)接正多邊形的實際運用如圖①,有一個寶塔,它的地基邊緣是周長為26m的正五邊形ABCDE(如圖②),點O為中心(下列各題結(jié)果精確到0.1m).(1)求地基的中心到邊緣的距離;(2)已知塔的墻體寬為1m,現(xiàn)要在塔的底層中心建一圓形底座的塑像,并且留出最窄處為1.6m的觀光通道,問塑像底座的半徑最大是多少?

  • 北師大初中九年級數(shù)學(xué)下冊直線和圓的位置關(guān)系及切線的性質(zhì)教案

    北師大初中九年級數(shù)學(xué)下冊直線和圓的位置關(guān)系及切線的性質(zhì)教案

    解析:(1)由切線的性質(zhì)得AB⊥BF,因為CD⊥AB,所以CD∥BF,由平行線的性質(zhì)得∠ADC=∠F,由圓周角定理的推論得∠ABC=∠ADC,于是證得∠ABC=∠F;(2)連接BD.由直徑所對的圓周角是直角得∠ADB=90°,因為∠ABF=90°,然后運用解直角三角形解答.(1)證明:∵BF為⊙O的切線,∴AB⊥BF.∵CD⊥AB,∴∠ABF=∠AHD=90°,∴CD∥BF.∴∠ADC=∠F.又∵∠ABC=∠ADC,∴∠ABC=∠F;(2)解:連接BD,∵AB為⊙O的直徑,∴∠ADB=90°,∴∠A+∠ABD=90°.由(1)可知∠ABF=90°,∴∠ABD+∠DBF=90°,∴∠A=∠DBF.又∵∠A=∠C,∴∠C=∠DBF.在Rt△DBF中,sin∠DBF=sinC=35,DF=6,∴BF=10,∴BD=8.在Rt△ABD中,sinA=sinC=35,BD=8,∴AB=403.∴⊙O的半徑為203.方法總結(jié):運用切線的性質(zhì)來進行計算或論證,常通過作輔助線連接圓心和切點,利用垂直構(gòu)造直角三角形解決有關(guān)問題.
