【教學(xué)目標(biāo)】(一)教學(xué)知識點能夠利用描點法作出函數(shù) 的圖象，并根據(jù)圖象認(rèn)識和理解二次函數(shù) 的性質(zhì)；比較兩者的異同.(二)能力訓(xùn)練要求：經(jīng)歷探索二次函數(shù) 圖象的作法和性質(zhì)的過程，獲得利用圖象研究函數(shù)性質(zhì)的經(jīng)驗.（三）情感態(tài)度與價值觀：通過學(xué)生自己的探索活動，達(dá)到對拋物線自身特點的認(rèn)識和對二次函數(shù)性質(zhì)的理解. 【重、難點】重點 ：會畫y=ax2的圖象，理解其性質(zhì)。難點：描點法畫y=ax2的圖象，體會數(shù)與形的相互聯(lián)系。 【導(dǎo)學(xué)流程】 一、自主預(yù)習(xí)（用時15分鐘）1.創(chuàng)設(shè)教學(xué)情境我們在教學(xué)了正比例函數(shù)、一次函數(shù)、反比例函數(shù)的定義后，都借助圖像研究了它們的性質(zhì).而上節(jié)課我們所學(xué)的二次函數(shù)的圖象是什么呢？本節(jié)課我們將從最簡單的二次函數(shù)y=x2入手去研究

解析：(1)已知拋物線解析式y(tǒng)＝ax2＋bx＋0.9，選定拋物線上兩點E(1，1.4)，B(6，0.9)，把坐標(biāo)代入解析式即可得出a、b的值，繼而得出拋物線解析式；(2)求出y＝1.575時，對應(yīng)的x的兩個值，從而可確定t的取值范圍．解：(1)由題意得點E的坐標(biāo)為(1，1.4)，點B的坐標(biāo)為(6，0.9)，代入y＝ax2＋bx＋0.9，得a＋b＋0.9＝1.4，36a＋6b＋0.9＝0.9，解得a＝－0.1，b＝0.6.故所求的拋物線的解析式為y＝－0.1x2＋0.6x＋0.9；(2)157.5cm＝1.575m，當(dāng)y＝1.575時，－0.1x2＋0.6x＋0.9＝1.575，解得x1＝32，x2＝92，則t的取值范圍為32＜t＜92.方法總結(jié)：解答本題的關(guān)鍵是注意審題，將實際問題轉(zhuǎn)化為求函數(shù)問題，培養(yǎng)自己利用數(shù)學(xué)知識解答實際問題的能力．三、板書設(shè)計二次函數(shù)y＝ax2＋bx＋c的圖象與性質(zhì)1．二次函數(shù)y＝ax2＋bx＋c的圖象與性質(zhì)2．二次函數(shù)y＝ax2＋bx＋c的應(yīng)用

北師大初中九年級數(shù)學(xué)下冊正切與坡度1教案
已知一水壩的橫斷面是梯形ABCD，下底BC長14m，斜坡AB的坡度為3∶3，另一腰CD與下底的夾角為45°，且長為46m，求它的上底的長(精確到0.1m，參考數(shù)據(jù)：2≈1.414，3≈1.732)．解析：過點A作AE⊥BC于E，過點D作DF⊥BC于F，根據(jù)已知條件求出AE＝DF的值，再根據(jù)坡度求出BE，最后根據(jù)EF＝BC－BE－FC求出AD.解：過點A作AE⊥BC，過點D作DF⊥BC，垂足分別為E、F.∵CD與BC的夾角為45°，∴∠DCF＝45°，∴∠CDF＝45°.∵CD＝46m，∴DF＝CF＝462＝43(m)，∴AE＝DF＝43m.∵斜坡AB的坡度為3∶3，∴tan∠ABE＝AEBE＝33＝3，∴BE＝4m.∵BC＝14m，∴EF＝BC－BE－CF＝14－4－43＝10－43(m)．∵AD＝EF，∴AD＝10－43≈3.1(m)．所以，它的上底的長約為3.1m.方法總結(jié)：考查對坡度的理解及梯形的性質(zhì)的掌握情況．解決問題的關(guān)鍵是添加輔助線構(gòu)造直角三角形．
