〖1/1算式〗
作业:求算式 90-arctan(0.12*10)-arctan(0.02*10)-arctan(5.83*10)+arctan(10) 的值.
题型:数学计算
解:
90-arctan(0.12*10)-arctan(0.02*10)-arctan(5.83*10)+arctan(10)
=90-arctan1.2-arctan(0.02*10)-arctan(5.83*10)+arctan(10)
=90-arctan1.2-arctan0.2-arctan(5.83*10)+arctan(10)
=90-arctan1.2-arctan0.2-arctan58.3+arctan(10)
=90-arctan1.2-arctan0.2-arctan58.3+arctan10
=90-0.876058-arctan0.2-arctan58.3+arctan10
=90-0.876058-0.197396-arctan58.3+arctan10
=90-0.876058-0.197396-1.553645+arctan10
=90-0.876058-0.197396-1.553645+1.471128
=89.123942-0.197396-1.553645+1.471128
=88.926546-1.553645+1.471128
=87.372901+1.471128
=88.844029 答案:90-arctan(0.12*10)-arctan(0.02*10)-arctan(5.83*10)+arctan(10)=88.844029 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!
