作业:求算式 90+arctan(23.5/4.8)-arctan(0.2*23.5)-arctan(0.0625*23.5)-arctan(23.5/115.2) 的值.
题型:数学计算
解:
90+arctan(23.5/4.8)-arctan(0.2*23.5)-arctan(0.0625*23.5)-arctan(23.5/115.2)
=90+arctan4.895833-arctan(0.2*23.5)-arctan(0.0625*23.5)-arctan(23.5/115.2)
=90+arctan4.895833-arctan4.7-arctan(0.0625*23.5)-arctan(23.5/115.2)
=90+arctan4.895833-arctan4.7-arctan1.46875-arctan(23.5/115.2)
=90+arctan4.895833-arctan4.7-arctan1.46875-arctan0.203993
=90+1.369312-arctan4.7-arctan1.46875-arctan0.203993
=90+1.369312-1.361156-arctan1.46875-arctan0.203993
=90+1.369312-1.361156-0.973038-arctan0.203993
=90+1.369312-1.361156-0.973038-0.201232
=91.369312-1.361156-0.973038-0.201232
=90.008156-0.973038-0.201232
=89.035118-0.201232
=88.833886 答案:90+arctan(23.5/4.8)-arctan(0.2*23.5)-arctan(0.0625*23.5)-arctan(23.5/115.2)=88.833886 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!
