圆的一般方程教学设计人教A版高中数学选择性必修第一册
情境导学前面我们已讨论了圆的标准方程为(x-a)2+(y-b)2=r2,现将其展开可得：x2+y2-2ax-2bx+a2+b2-r2=0.可见,任何一个圆的方程都可以变形x2+y2+Dx+Ey+F=0的形式.请大家思考一下,形如x2+y2+Dx+Ey+F=0的方程表示的曲线是不是圆?下面我们来探讨这一方面的问题.探究新知例如,对于方程x^2+y^2-2x-4y+6=0,对其进行配方，得〖(x-1)〗^2+(〖y-2)〗^2=-1,因为任意一点的坐标 (x,y) 都不满足这个方程，所以这个方程不表示任何图形，所以形如x2+y2+Dx+Ey+F=0的方程不一定能通过恒等变换为圆的标准方程，这表明形如x2+y2+Dx+Ey+F=0的方程不一定是圆的方程.一、圆的一般方程（1）当D2+E2-4F>0时,方程x2+y2+Dx+Ey+F=0表示以(-D/2,-E/2)为圆心,1/2 √(D^2+E^2 "-" 4F)为半径的圆,将方程x2+y2+Dx+Ey+F=0，配方可得〖(x+D/2)〗^2+(〖y+E/2)〗^2=(D^2+E^2-4F)/4（2）当D2+E2-4F=0时,方程x2+y2+Dx+Ey+F=0，表示一个点(-D/2,-E/2)（3）当D2+E2-4F0);

直线与圆的位置关系教学设计人教A版高中数学选择性必修第一册
切线方程的求法1.求过圆上一点P(x0,y0)的圆的切线方程:先求切点与圆心连线的斜率k,则由垂直关系,切线斜率为-1/k,由点斜式方程可求得切线方程.若k=0或斜率不存在,则由图形可直接得切线方程为y=b或x=a.2.求过圆外一点P(x0,y0)的圆的切线时,常用几何方法求解设切线方程为y-y0=k(x-x0),即kx-y-kx0+y0=0,由圆心到直线的距离等于半径,可求得k,进而切线方程即可求出.但要注意,此时的切线有两条,若求出的k值只有一个时,则另一条切线的斜率一定不存在,可通过数形结合求出.例3 求直线l:3x+y-6=0被圆C:x2+y2-2y-4=0截得的弦长.思路分析:解法一求出直线与圆的交点坐标,解法二利用弦长公式,解法三利用几何法作出直角三角形,三种解法都可求得弦长.解法一由{■(3x+y"-" 6=0"," @x^2+y^2 "-" 2y"-" 4=0"," )┤得交点A(1,3),B(2,0),故弦AB的长为|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.设两交点A,B的坐标分别为A(x1,y1),B(x2,y2),则由根与系数的关系,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的长为√10.解法三圆C:x2+y2-2y-4=0可化为x2+(y-1)2=5,其圆心坐标(0,1),半径r=√5,点(0,1)到直线l的距离为d=("|" 3×0+1"-" 6"|" )/√(3^2+1^2 )=√10/2,所以半弦长为("|" AB"|" )/2=√(r^2 "-" d^2 )=√("(" √5 ")" ^2 "-" (√10/2) ^2 )=√10/2,所以弦长|AB|=√10.
空间向量基本定理教学设计人教A版高中数学选择性必修第一册
反思感悟用基底表示空间向量的解题策略1.空间中,任一向量都可以用一个基底表示,且只要基底确定,则表示形式是唯一的.2.用基底表示空间向量时,一般要结合图形,运用向量加法、减法的平行四边形法则、三角形法则,以及数乘向量的运算法则,逐步向基向量过渡,直至全部用基向量表示.3.在空间几何体中选择基底时,通常选取公共起点最集中的向量或关系最明确的向量作为基底,例如,在正方体、长方体、平行六面体、四面体中,一般选用从同一顶点出发的三条棱所对应的向量作为基底.例2.在棱长为2的正方体ABCD-A1B1C1D1中,E,F分别是DD1,BD的中点,点G在棱CD上,且CG=1/3 CD(1)证明:EF⊥B1C;(2)求EF与C1G所成角的余弦值.思路分析选择一个空间基底,将(EF) ?,(B_1 C) ?,(C_1 G) ?用基向量表示.(1)证明(EF) ?·(B_1 C) ?=0即可;(2)求(EF) ?与(C_1 G) ?夹角的余弦值即可.(1)证明:设(DA) ?=i,(DC) ?=j,(DD_1 ) ?=k,则{i,j,k}构成空间的一个正交基底.

4.已知△ABC三个顶点坐标A(－1,3)，B(－3,0)，C(1,2)，求△ABC的面积S.【解析】由直线方程的两点式得直线BC的方程为 ＝ ，即x－2y＋3＝0，由两点间距离公式得|BC|＝ ，点A到BC的距离为d，即为BC边上的高，d＝ ，所以S＝ |BC|·d＝ ×2 × ＝4，即△ABC的面积为4.5.已知直线l经过点P(0,2),且A(1,1),B(-3,1)两点到直线l的距离相等,求直线l的方程.解:(方法一)∵点A(1,1)与B(-3,1)到y轴的距离不相等,∴直线l的斜率存在,设为k.又直线l在y轴上的截距为2,则直线l的方程为y=kx+2,即kx-y+2=0.由点A(1,1)与B(-3,1)到直线l的距离相等,∴直线l的方程是y=2或x-y+2=0.得("|" k"-" 1+2"|" )/√(k^2+1)=("|-" 3k"-" 1+2"|" )/√(k^2+1),解得k=0或k=1.(方法二)当直线l过线段AB的中点时,A,B两点到直线l的距离相等.∵AB的中点是(-1,1),又直线l过点P(0,2),∴直线l的方程是x-y+2=0.当直线l∥AB时,A,B两点到直线l的距离相等.∵直线AB的斜率为0,∴直线l的斜率为0,∴直线l的方程为y=2.综上所述,满足条件的直线l的方程是x-y+2=0或y=2.
