〖1/1算式〗
作业:求算式 90+arctan(0.6*19.2)-arctan(0.25*0.6)-arctan(0.6)-arctan(160*0.6) 的值.
题型:数学计算
解:
90+arctan(0.6*19.2)-arctan(0.25*0.6)-arctan(0.6)-arctan(160*0.6)
=90+arctan11.52-arctan(0.25*0.6)-arctan(0.6)-arctan(160*0.6)
=90+arctan11.52-arctan0.15-arctan(0.6)-arctan(160*0.6)
=90+arctan11.52-arctan0.15-arctan0.6-arctan(160*0.6)
=90+arctan11.52-arctan0.15-arctan0.6-arctan96
=90+1.484208-arctan0.15-arctan0.6-arctan96
=90+1.484208-0.14889-arctan0.6-arctan96
=90+1.484208-0.14889-0.54042-arctan96
=90+1.484208-0.14889-0.54042-1.56038
=91.484208-0.14889-0.54042-1.56038
=91.335318-0.54042-1.56038
=90.794898-1.56038
=89.234518 答案:90+arctan(0.6*19.2)-arctan(0.25*0.6)-arctan(0.6)-arctan(160*0.6)=89.234518 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!
