高三数学（理）一轮复习ppt课件第27讲数系的扩充与复数的引入.pptx

教学参考课前双基巩固课堂考点探究教师备用例题,1.理解复数的基本概念,理解复数相等的充要条件.2.了解复数的代数表示法及其几何意义;能将代数形式的复数在复平面上用点或向量表示,并能将复平面上的点或向量所对应的复数用代数形式表示.3.能进行复数代数形式的四则运算,了解两个具体复数相加、相减的几何意义.,考试说明,考情分析,真题再现,20172013课标全国真题再现,2017-2016其他省份类似高考真题,知识聚焦,虚部,实部,b=0,b0,a=0且 b0,a=c且b=d,a=c且b=-d,|z|,|a+bi|,(a-c)+(b-d)i,(a+c)+(b+d)i,z2+z1,(ac-bd)+(ad+bc)i,z1+(z2+z3),对点演练,题组一常识题,题组二常错题,索引:将复数a+bi(a,bR)的虚部误认为是bi;将复数在复平面内所对应的点的位置弄错;错用虚数单位i的幂的性质.,探究点一复数的有关概念,探究点二复数的几何意义,探究点三复数的代数运算,【备选理由】例1考查复数的概念与复数的运算;例2考查复数的几何意义;例3考查复数的运算、复数相等的条件、模的运算的综合.,dsfdbsy384y982ythb3oibt4oy39y409705923y09y53b2lkboi2y58wy0ehtoibwoify98wy049ywh4b3oiut89u983yf9ivh98y98sv98hv98ys9f698y9v698yv98x98tb98fyd98gyd98h98ds98nt98d8genklgb4klebtlkb5k tkeirh893y89ey698vhkrne lkhgi8eyokbnkdhf98hodf hxvy78fd678t9fdu90gys98y9shihixyv78dfhvifndovhf9f8yv9onvkobkw kjfegiudsfdbsy384y982ythb3oibt4oy39y409705923y09y53b2lkboi2y58wy0ehtoibwoify98wy049ywh4b3oiut89u983yf9ivh98y98sv98hv98ys9f698y9v698yv98x98tb98fyd98gyd98h98ds98nt98d8genklgb4klebtlkb5k tkeirh893y89ey698vhkrne lkhgi8eyokbnkdhf98hodf hxvy78fd678t9fdu90gys98y9shihixyv78dfhvifndovhf9f8yv9onvkobkw kjfegiudsfdbsy384y982ythb3oibt4oy39y409705923y09y53b2lkboi2y58wy0ehtoibwoify98wy049ywh4b3oiut89u983yf9ivh98y98sv98hv98ys9f698y9v698yv98x98tb98fyd98gyd98h98ds98nt98d8gen,56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm,56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm56384866666gjfdghmghm,￥1111111111111111111111111111111222222222222222222222222222222222222222222222222222222223333333333333333333333333333333333333333333333333333333333333333333344444￥,
