〖1/1算式〗
作业:求算式 90-arctan(0.1*91)-arctan(0.01*91)+arctan(0.052*91)-arctan(0.004*91) 的值.
题型:数学计算
解:
90-arctan(0.1*91)-arctan(0.01*91)+arctan(0.052*91)-arctan(0.004*91)
=90-arctan9.1-arctan(0.01*91)+arctan(0.052*91)-arctan(0.004*91)
=90-arctan9.1-arctan0.91+arctan(0.052*91)-arctan(0.004*91)
=90-arctan9.1-arctan0.91+arctan4.732-arctan(0.004*91)
=90-arctan9.1-arctan0.91+arctan4.732-arctan0.364
=90-1.461345-arctan0.91+arctan4.732-arctan0.364
=90-1.461345-0.738313+arctan4.732-arctan0.364
=90-1.461345-0.738313+1.362533-arctan0.364
=90-1.461345-0.738313+1.362533-0.349092
=88.538655-0.738313+1.362533-0.349092
=87.800342+1.362533-0.349092
=89.162875-0.349092
=88.813783 答案:90-arctan(0.1*91)-arctan(0.01*91)+arctan(0.052*91)-arctan(0.004*91)=88.813783 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!
