〖1/1算式〗
作业:求算式 arctan(0.15*18.76)+90-arctan(0.2*18.76)-arctan(0.02*18.76)-arctan(0.0625*18.76) 的值.
题型:数学计算
解:
arctan(0.15*18.76)+90-arctan(0.2*18.76)-arctan(0.02*18.76)-arctan(0.0625*18.76)
=arctan2.814+90-arctan(0.2*18.76)-arctan(0.02*18.76)-arctan(0.0625*18.76)
=arctan2.814+90-arctan3.752-arctan(0.02*18.76)-arctan(0.0625*18.76)
=arctan2.814+90-arctan3.752-arctan0.3752-arctan(0.0625*18.76)
=arctan2.814+90-arctan3.752-arctan0.3752-arctan1.1725
=1.229349+90-arctan3.752-arctan0.3752-arctan1.1725
=1.229349+90-1.310327-arctan0.3752-arctan1.1725
=1.229349+90-1.310327-0.358946-arctan1.1725
=1.229349+90-1.310327-0.358946-0.864634
=91.229349-1.310327-0.358946-0.864634
=89.919022-0.358946-0.864634
=89.560076-0.864634
=88.695442 答案:arctan(0.15*18.76)+90-arctan(0.2*18.76)-arctan(0.02*18.76)-arctan(0.0625*18.76)=88.695442 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!
