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
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＝πOB2－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
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．
