〖1/1算式〗
作业:求算式 90+arctan(0.97*0.24)-arctan(0.1*0.24)-arctan(0.01*0.24)-arctan(17.16*0.24) 的值.
题型:数学计算
解:
90+arctan(0.97*0.24)-arctan(0.1*0.24)-arctan(0.01*0.24)-arctan(17.16*0.24)
=90+arctan0.2328-arctan(0.1*0.24)-arctan(0.01*0.24)-arctan(17.16*0.24)
=90+arctan0.2328-arctan0.024-arctan(0.01*0.24)-arctan(17.16*0.24)
=90+arctan0.2328-arctan0.024-arctan0.0024-arctan(17.16*0.24)
=90+arctan0.2328-arctan0.024-arctan0.0024-arctan4.1184
=90+0.228726-arctan0.024-arctan0.0024-arctan4.1184
=90+0.228726-0.023995-arctan0.0024-arctan4.1184
=90+0.228726-0.023995-0.0024-arctan4.1184
=90+0.228726-0.023995-0.0024-1.332593
=90.228726-0.023995-0.0024-1.332593
=90.204731-0.0024-1.332593
=90.202331-1.332593
=88.869738 答案:90+arctan(0.97*0.24)-arctan(0.1*0.24)-arctan(0.01*0.24)-arctan(17.16*0.24)=88.869738 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!
