〖1/1算式〗
作业:求算式 arctan(6/2)+arctan(6/6)-arctan(6/12)-arctan(6/60)-arctan(6/80) 的值.
题型:数学计算
解:
arctan(6/2)+arctan(6/6)-arctan(6/12)-arctan(6/60)-arctan(6/80)
=arctan3+arctan(6/6)-arctan(6/12)-arctan(6/60)-arctan(6/80)
=arctan3+arctan1-arctan(6/12)-arctan(6/60)-arctan(6/80)
=arctan3+arctan1-arctan0.5-arctan(6/60)-arctan(6/80)
=arctan3+arctan1-arctan0.5-arctan0.1-arctan(6/80)
=arctan3+arctan1-arctan0.5-arctan0.1-arctan0.075
=1.249046+arctan1-arctan0.5-arctan0.1-arctan0.075
=1.249046+0.785398-arctan0.5-arctan0.1-arctan0.075
=1.249046+0.785398-0.463648-arctan0.1-arctan0.075
=1.249046+0.785398-0.463648-0.099669-arctan0.075
=1.249046+0.785398-0.463648-0.099669-0.07486
=2.034444-0.463648-0.099669-0.07486
=1.570796-0.099669-0.07486
=1.471127-0.07486
=1.396267 答案:arctan(6/2)+arctan(6/6)-arctan(6/12)-arctan(6/60)-arctan(6/80)=1.396267 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!
