〖1/1算式〗
作业:求算式 180+arctan(2*3^0.5/(-2))+arctan(2*3^0.5/(1-2))+arctan(2*3^0.5/(10-2)) 的值.
题型:数学计算
解:
180+arctan(2*3^0.5/(-2))+arctan(2*3^0.5/(1-2))+arctan(2*3^0.5/(10-2))
=180+arctan(2*3^0.5/(-2))+arctan(2*3^0.5/(1-2))+arctan(2*3^0.5/(10-2))
=180+arctan(-1.732051)+arctan(2*3^0.5/(1-2))+arctan(2*3^0.5/(10-2))
=180+arctan-1.732051+arctan(2*3^0.5/(-1))+arctan(2*3^0.5/(10-2))
=180+arctan-1.732051+arctan(-3.464102)+arctan(2*3^0.5/(10-2))
=180+arctan-1.732051+arctan-3.464102+arctan(2*3^0.5/8)
=180+arctan-1.732051+arctan-3.464102+arctan0.433013
=180+-1.047198+arctan-3.464102+arctan0.433013
=180+-1.047198+-1.289761+arctan0.433013
=180+-1.047198+-1.289761+0.408638
=178.952802+(-1.289761)+0.408638
=177.663041+0.408638
=178.071679 答案:180+arctan(2*3^0.5/(-2))+arctan(2*3^0.5/(1-2))+arctan(2*3^0.5/(10-2))=178.071679 注:弧度制你的问题在这里没有得到解决?请到 热门难题 里面看看吧!
