直線與圓的位置關(guān)系教學(xué)設(shè)計(jì)人教A版高中數(shù)學(xué)選擇性必修第一冊(cè)
切線方程的求法1.求過(guò)圓上一點(diǎn)P(x0,y0)的圓的切線方程:先求切點(diǎn)與圓心連線的斜率k,則由垂直關(guān)系,切線斜率為-1/k,由點(diǎn)斜式方程可求得切線方程.若k=0或斜率不存在,則由圖形可直接得切線方程為y=b或x=a.2.求過(guò)圓外一點(diǎn)P(x0,y0)的圓的切線時(shí),常用幾何方法求解設(shè)切線方程為y-y0=k(x-x0),即kx-y-kx0+y0=0,由圓心到直線的距離等于半徑,可求得k,進(jìn)而切線方程即可求出.但要注意,此時(shí)的切線有兩條,若求出的k值只有一個(gè)時(shí),則另一條切線的斜率一定不存在,可通過(guò)數(shù)形結(jié)合求出.例3 求直線l:3x+y-6=0被圓C:x2+y2-2y-4=0截得的弦長(zhǎng).思路分析:解法一求出直線與圓的交點(diǎn)坐標(biāo),解法二利用弦長(zhǎng)公式,解法三利用幾何法作出直角三角形,三種解法都可求得弦長(zhǎng).解法一由{■(3x+y"-" 6=0"," @x^2+y^2 "-" 2y"-" 4=0"," )┤得交點(diǎn)A(1,3),B(2,0),故弦AB的長(zhǎng)為|AB|=√("(" 2"-" 1")" ^2+"(" 0"-" 3")" ^2 )=√10.解法二由{■(3x+y"-" 6=0"," @x^2+y^2 "-" 2y"-" 4=0"," )┤消去y,得x2-3x+2=0.設(shè)兩交點(diǎn)A,B的坐標(biāo)分別為A(x1,y1),B(x2,y2),則由根與系數(shù)的關(guān)系,得x1+x2=3,x1·x2=2.∴|AB|=√("(" x_2 "-" x_1 ")" ^2+"(" y_2 "-" y_1 ")" ^2 )=√(10"[(" x_1+x_2 ")" ^2 "-" 4x_1 x_2 "]" ┴" " )=√(10×"(" 3^2 "-" 4×2")" )=√10,即弦AB的長(zhǎng)為√10.解法三圓C:x2+y2-2y-4=0可化為x2+(y-1)2=5,其圓心坐標(biāo)(0,1),半徑r=√5,點(diǎn)(0,1)到直線l的距離為d=("|" 3×0+1"-" 6"|" )/√(3^2+1^2 )=√10/2,所以半弦長(zhǎng)為("|" AB"|" )/2=√(r^2 "-" d^2 )=√("(" √5 ")" ^2 "-" (√10/2) ^2 )=√10/2,所以弦長(zhǎng)|AB|=√10.
人教版高中歷史必修2物質(zhì)生活與習(xí)俗的變遷說(shuō)課稿2篇
【課外延伸】閱讀思考：1、改革開放以來(lái)，東西方文明的交流、碰撞更加劇烈。對(duì)于外來(lái)文化，目前有不同的觀點(diǎn)，現(xiàn)引入兩種觀點(diǎn)：觀點(diǎn)1：這是一種進(jìn)步。改革開放以來(lái)，中國(guó)不斷發(fā)展，這時(shí)候舊的文化顯然是不合時(shí)宜的，西方文化的進(jìn)入，給我們帶來(lái)了新的生活方式和生活態(tài)度，中國(guó)逐漸改掉了一些陋習(xí)，與世界接軌。觀點(diǎn)2：這是一種文化侵略。西方文化的進(jìn)入，使中國(guó)傳統(tǒng)文化一步步淪喪，特別是我們過(guò)著西方圣誕節(jié)時(shí)，中國(guó)的傳統(tǒng)節(jié)日端午節(jié)已被韓國(guó)申報(bào)為非物質(zhì)文化遺產(chǎn)。這告訴我們，我們應(yīng)該保護(hù)我們的傳統(tǒng)文化。面對(duì)東西方文化的交匯、碰撞，你認(rèn)為該怎樣正確看待外來(lái)文化和傳統(tǒng)文化？請(qǐng)寫篇小論文闡述你的觀點(diǎn)。2、設(shè)計(jì)以下表格：利用搜集的資料按照“衣、食、住、行、風(fēng)俗”五部分進(jìn)行比較，再將現(xiàn)代社會(huì)物質(zhì)生活和習(xí)俗細(xì)分為“辛亥革命前和辛亥革命后”兩部分內(nèi)容進(jìn)行比較。
人教版高中歷史必修1羅馬法的起源與發(fā)展說(shuō)課稿
學(xué)生思考回答后歸納：隨著征服地區(qū)的擴(kuò)大，出現(xiàn)了許多新問(wèn)題，新矛盾，原有的公民法已經(jīng)無(wú)法適應(yīng)這些新變化（質(zhì)疑）。公民法適用范圍限于羅馬公民，用來(lái)調(diào)整他們之間的關(guān)系，羅馬公民受到法律保護(hù)，并享受法律賦予的權(quán)利。在擴(kuò)張中納入到疆域中的許多外邦人不能受到法律的保護(hù)，在這種背景下，公民法發(fā)展成萬(wàn)民法。萬(wàn)民法的出現(xiàn)，一方面由于公民法的狹隘性，另一方面伴隨對(duì)外戰(zhàn)爭(zhēng)的勝利，奴隸制在羅馬得到快速發(fā)展。為了更加有效地保護(hù)奴隸主的私人利益，迫切需要建立和完善法律制度來(lái)維護(hù)統(tǒng)治階級(jí)的利益不受侵犯。問(wèn)題探究：萬(wàn)民法的制定產(chǎn)生哪些作用？學(xué)生思考回答后總結(jié)：萬(wàn)民法取代公民法，協(xié)調(diào)了羅馬人和外邦人之間的關(guān)系及外邦人相互之間的關(guān)系，對(duì)于在龐大帝國(guó)內(nèi)微細(xì)，協(xié)調(diào)各地區(qū)的民族關(guān)系、社會(huì)矛盾也祈禱重要作用。萬(wàn)民法使法律具有了更大的適用范圍，也成為鞏固羅馬統(tǒng)治的重要工具。
人教版高中歷史必修2殖民擴(kuò)張與世界市場(chǎng)的拓展說(shuō)課稿2篇
精講拓寬：師：（精講）英國(guó)位于大西洋中的不列顛島上，東、南隔北海、多佛爾海峽、英吉利海峽與歐洲大陸相望，具備了擴(kuò)大海外貿(mào)易的得天獨(dú)厚的條件。新航路開辟以后，歐洲的商路和貿(mào)易中心發(fā)生了變化，主要商路從地中海轉(zhuǎn)移到大西洋沿岸。英國(guó)積極參與了海外貿(mào)易的競(jìng)爭(zhēng)。請(qǐng)同學(xué)們思考：英國(guó)資本主義是怎樣發(fā)展起來(lái)的呢？生1：像荷蘭一樣，英國(guó)位于大西洋沿岸，具備了擴(kuò)大海外貿(mào)易的得天獨(dú)厚的條件。生2：更主要的是英國(guó)政府組建了東印度公司，大力發(fā)展海外貿(mào)易，進(jìn)行海外殖民擴(kuò)張。生3：英國(guó)是島國(guó)，在資產(chǎn)階級(jí)革命以后建立起來(lái)的資產(chǎn)階級(jí)政府，十分重視海軍建設(shè)，為爭(zhēng)奪殖民地提供了軍事保障。生4：還有一個(gè)原因不能忽視，那就是英國(guó)的煤炭和羊毛資源豐富，手工業(yè)發(fā)達(dá)，為它的海外殖民活動(dòng)奠定了雄厚的物質(zhì)基礎(chǔ)。師：（過(guò)渡）其實(shí)，英國(guó)資本主義的發(fā)展過(guò)程，就是它殖民霸權(quán)地位的確立過(guò)程，也就是與其他殖民國(guó)家不斷斗爭(zhēng)并取得勝利的過(guò)程。英國(guó)先后與哪些國(guó)家發(fā)生過(guò)爭(zhēng)奪戰(zhàn)爭(zhēng)呢？
