作业:求算式 180+arctan(0.4*52.759)-90-arctan(0.2*52.759)-arctan(0.5*52.759)-arctan(0.08*52.759) 的值.
题型:数学计算
解:
180+arctan(0.4*52.759)-90-arctan(0.2*52.759)-arctan(0.5*52.759)-arctan(0.08*52.759)
=180+arctan21.1036-90-arctan(0.2*52.759)-arctan(0.5*52.759)-arctan(0.08*52.759)
=180+arctan21.1036-90-arctan10.5518-arctan(0.5*52.759)-arctan(0.08*52.759)
=180+arctan21.1036-90-arctan10.5518-arctan26.3795-arctan(0.08*52.759)
=180+arctan21.1036-90-arctan10.5518-arctan26.3795-arctan4.22072
=180+1.523446-90-arctan10.5518-arctan26.3795-arctan4.22072
=180+1.523446-90-1.476308-arctan26.3795-arctan4.22072
=180+1.523446-90-1.476308-1.532906-arctan4.22072
=180+1.523446-90-1.476308-1.532906-1.33816
=181.523446-90-1.476308-1.532906-1.33816
=91.523446-1.476308-1.532906-1.33816
=90.047138-1.532906-1.33816
=88.514232-1.33816
=87.176072 答案:180+arctan(0.4*52.759)-90-arctan(0.2*52.759)-arctan(0.5*52.759)-arctan(0.08*52.759)=87.176072 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!
