〖1/1算式〗
作业:求算式 90+arctan(0.12*17.13)-arctan(0.2*17.13)-arctan(0.012*17.13)-arctan(0.0625*17.13) 的值.
题型:数学计算
解:
90+arctan(0.12*17.13)-arctan(0.2*17.13)-arctan(0.012*17.13)-arctan(0.0625*17.13)
=90+arctan2.0556-arctan(0.2*17.13)-arctan(0.012*17.13)-arctan(0.0625*17.13)
=90+arctan2.0556-arctan3.426-arctan(0.012*17.13)-arctan(0.0625*17.13)
=90+arctan2.0556-arctan3.426-arctan0.20556-arctan(0.0625*17.13)
=90+arctan2.0556-arctan3.426-arctan0.20556-arctan1.070625
=90+1.118026-arctan3.426-arctan0.20556-arctan1.070625
=90+1.118026-1.2868-arctan0.20556-arctan1.070625
=90+1.118026-1.2868-0.202736-arctan1.070625
=90+1.118026-1.2868-0.202736-0.819493
=91.118026-1.2868-0.202736-0.819493
=89.831226-0.202736-0.819493
=89.62849-0.819493
=88.808997 答案:90+arctan(0.12*17.13)-arctan(0.2*17.13)-arctan(0.012*17.13)-arctan(0.0625*17.13)=88.808997 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!
