〖1/1算式〗
作业:求算式 180+arctan(6*3^0.5/(-6))+arctan(6*3^0.5/(5-6))+arctan(6*3^0.5/(20-6)) 的值.
题型:数学计算
解:
180+arctan(6*3^0.5/(-6))+arctan(6*3^0.5/(5-6))+arctan(6*3^0.5/(20-6))
=180+arctan(6*3^0.5/(-6))+arctan(6*3^0.5/(5-6))+arctan(6*3^0.5/(20-6))
=180+arctan(-1.732051)+arctan(6*3^0.5/(5-6))+arctan(6*3^0.5/(20-6))
=180+arctan-1.732051+arctan(6*3^0.5/(-1))+arctan(6*3^0.5/(20-6))
=180+arctan-1.732051+arctan(-10.392305)+arctan(6*3^0.5/(20-6))
=180+arctan-1.732051+arctan-10.392305+arctan(6*3^0.5/14)
=180+arctan-1.732051+arctan-10.392305+arctan0.742308
=180+-1.047198+arctan-10.392305+arctan0.742308
=180+-1.047198+-1.474867+arctan0.742308
=180+-1.047198+-1.474867+0.63856
=178.952802+(-1.474867)+0.63856
=177.477935+0.63856
=178.116495 答案:180+arctan(6*3^0.5/(-6))+arctan(6*3^0.5/(5-6))+arctan(6*3^0.5/(20-6))=178.116495 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!
