作业:求算式 arctan(4.17*2.41)+90-arctan(61.9662*2.41)-arctan(0.2*2.41)-arctan(0.0625*2.41) 的值.
题型:数学计算
解:
arctan(4.17*2.41)+90-arctan(61.9662*2.41)-arctan(0.2*2.41)-arctan(0.0625*2.41)
=arctan10.0497+90-arctan(61.9662*2.41)-arctan(0.2*2.41)-arctan(0.0625*2.41)
=arctan10.0497+90-arctan149.338542-arctan(0.2*2.41)-arctan(0.0625*2.41)
=arctan10.0497+90-arctan149.338542-arctan0.482-arctan(0.0625*2.41)
=arctan10.0497+90-arctan149.338542-arctan0.482-arctan0.150625
=1.471617+90-arctan149.338542-arctan0.482-arctan0.150625
=1.471617+90-1.5641-arctan0.482-arctan0.150625
=1.471617+90-1.5641-0.449144-arctan0.150625
=1.471617+90-1.5641-0.449144-0.149501
=91.471617-1.5641-0.449144-0.149501
=89.907517-0.449144-0.149501
=89.458373-0.149501
=89.308872 答案:arctan(4.17*2.41)+90-arctan(61.9662*2.41)-arctan(0.2*2.41)-arctan(0.0625*2.41)=89.308872 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!
