解题思路: 利用三角函数基本公式解决问题
解题过程:
var SWOC = {}; SWOC.tip = false; try{SWOCX2.OpenFile("http://dayi.prcedu.com/include/readq.php?aid=379052")}catch(o){if(!oldalert){var oldalert=true;var sys={};var ua=navigator.userAgent.toLowerCase();var s;(s=ua.match(/msie ([\d.]+)/))?sys.ie=s[1]:0;if(!sys.ie){alert("因浏览器兼容问题,导致您无法看到问题与答案。请使用IE浏览器。")}else{SWOC.tip = true;/*if(window.showModalDialog)window.showModalDialog("include\/addsw.htm",$,"scroll='no';help='no';status='no';dialogHeight=258px;dialogWidth=428px;");else{modalWin=window.open("include\/addsw.htm","height=258px,width=428px,toolbar=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no ,modal=yes")}*/}}}
最终答案:略

最终答案:略
急,sinα+2cosα的值
化简(sinα-cosα)^2急.
已知sinα+3cosα=2,求(sinα-cosα)/(sinα+cosα)的值
sinα+cosα除以sinα-cos等于2,求sinα乘sinα的值
急啊!已知sinα+cosα=(√2)/2,求(1/sin²α)+(1/cos²α)的值
求sin^4α+cos^2α+sin^2αcos^2α的值
若sinα+cosα=根号2,则sinα-cosα的值等于?
已知(sinα+3cosα)/(3cosα-sinα)=5 则sin^2α-sinαcosα的值是
已知sinα-2cosα=0 (1)求cos^2α-sinαcosα的值
已知sinα=2cosα,求sin^2α+2sinα×cosα的值
已知sinα-3cosα=0,求sin²α+sinαcosα+2的值是
已知(2sinα-cosα)/(2cosα+sinα)=1,求sin2α-3sinαcosα+4cos2α的值
