作业:求算式 90+arctan(0.33*41)+arctan(0.68*41)-arctan(4.1)-arctan(0.41)-arctan(1.75*41)-arctan(0.17*41) 的值.
题型:数学计算
解:
90+arctan(0.33*41)+arctan(0.68*41)-arctan(4.1)-arctan(0.41)-arctan(1.75*41)-arctan(0.17*41)
=90+arctan13.53+arctan(0.68*41)-arctan(4.1)-arctan(0.41)-arctan(1.75*41)-arctan(0.17*41)
=90+arctan13.53+arctan27.88-arctan(4.1)-arctan(0.41)-arctan(1.75*41)-arctan(0.17*41)
=90+arctan13.53+arctan27.88-arctan4.1-arctan(0.41)-arctan(1.75*41)-arctan(0.17*41)
=90+arctan13.53+arctan27.88-arctan4.1-arctan0.41-arctan(1.75*41)-arctan(0.17*41)
=90+arctan13.53+arctan27.88-arctan4.1-arctan0.41-arctan71.75-arctan(0.17*41)
=90+arctan13.53+arctan27.88-arctan4.1-arctan0.41-arctan71.75-arctan6.97
=90+1.497021+arctan27.88-arctan4.1-arctan0.41-arctan71.75-arctan6.97
=90+1.497021+1.534944-arctan4.1-arctan0.41-arctan71.75-arctan6.97
=90+1.497021+1.534944-1.331565-arctan0.41-arctan71.75-arctan6.97
=90+1.497021+1.534944-1.331565-0.389097-arctan71.75-arctan6.97
=90+1.497021+1.534944-1.331565-0.389097-1.55686-arctan6.97
=90+1.497021+1.534944-1.331565-0.389097-1.55686-1.428297
=91.497021+1.534944-1.331565-0.389097-1.55686-1.428297
=93.031965-1.331565-0.389097-1.55686-1.428297
=91.7004-0.389097-1.55686-1.428297
=91.311303-1.55686-1.428297
=89.754443-1.428297
=88.326146 答案:90+arctan(0.33*41)+arctan(0.68*41)-arctan(4.1)-arctan(0.41)-arctan(1.75*41)-arctan(0.17*41)=88.326146 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!
