〖1/1算式〗
作业:求算式 -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:
-arctan(6*3^0.5/(-6))-arctan(6*3^0.5/(5-6))-arctan(6*3^0.5/(20-6))
=-arctan(6*3^0.5/(-6))-arctan(6*3^0.5/(5-6))-arctan(6*3^0.5/(20-6))
=-arctan(-1.732051)-arctan(6*3^0.5/(5-6))-arctan(6*3^0.5/(20-6))
=-arctan-1.732051-arctan(6*3^0.5/(-1))-arctan(6*3^0.5/(20-6))
=-arctan-1.732051-arctan(-10.392305)-arctan(6*3^0.5/(20-6))
=-arctan-1.732051-arctan-10.392305-arctan(6*3^0.5/14)
=-arctan-1.732051-arctan-10.392305-arctan0.742308
=--1.047198-arctan-10.392305-arctan0.742308
=--1.047198--1.474867-arctan0.742308
=--1.047198--1.474867-0.63856
=1.474867-0.63856
=0.836307 答案:-arctan(6*3^0.5/(-6))-arctan(6*3^0.5/(5-6))-arctan(6*3^0.5/(20-6))=0.836307 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!
