〖1/1算式〗
作业:求算式 arctan(3*0.237)-90-arctan(6*0.237)-arctan(10*0.237)-arctan(4*0.237/25) 的值.
题型:数学计算
解:
arctan(3*0.237)-90-arctan(6*0.237)-arctan(10*0.237)-arctan(4*0.237/25)
=arctan0.711-90-arctan(6*0.237)-arctan(10*0.237)-arctan(4*0.237/25)
=arctan0.711-90-arctan1.422-arctan(10*0.237)-arctan(4*0.237/25)
=arctan0.711-90-arctan1.422-arctan2.37-arctan(4*0.237/25)
=arctan0.711-90-arctan1.422-arctan2.37-arctan0.03792
=0.61807-90-arctan1.422-arctan2.37-arctan0.03792
=0.61807-90-0.957903-arctan2.37-arctan0.03792
=0.61807-90-0.957903-1.17152-arctan0.03792
=0.61807-90-0.957903-1.17152-0.037902
=-89.38193-0.957903-1.17152-0.037902
=-90.339833-1.17152-0.037902
=-91.511353-0.037902
=-91.549255 答案:arctan(3*0.237)-90-arctan(6*0.237)-arctan(10*0.237)-arctan(4*0.237/25)=-91.549255 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!
