作业:求算式 arctan(0.77*13)+90-arctan(0.1*13)-arctan(0.01*13)-arctan(0.02*13)-arctan(13*9.1) 的值.
题型:数学计算
解:
arctan(0.77*13)+90-arctan(0.1*13)-arctan(0.01*13)-arctan(0.02*13)-arctan(13*9.1)
=arctan10.01+90-arctan(0.1*13)-arctan(0.01*13)-arctan(0.02*13)-arctan(13*9.1)
=arctan10.01+90-arctan1.3-arctan(0.01*13)-arctan(0.02*13)-arctan(13*9.1)
=arctan10.01+90-arctan1.3-arctan0.13-arctan(0.02*13)-arctan(13*9.1)
=arctan10.01+90-arctan1.3-arctan0.13-arctan0.26-arctan(13*9.1)
=arctan10.01+90-arctan1.3-arctan0.13-arctan0.26-arctan118.3
=1.471227+90-arctan1.3-arctan0.13-arctan0.26-arctan118.3
=1.471227+90-0.915101-arctan0.13-arctan0.26-arctan118.3
=1.471227+90-0.915101-0.129275-arctan0.26-arctan118.3
=1.471227+90-0.915101-0.129275-0.254368-arctan118.3
=1.471227+90-0.915101-0.129275-0.254368-1.562343
=91.471227-0.915101-0.129275-0.254368-1.562343
=90.556126-0.129275-0.254368-1.562343
=90.426851-0.254368-1.562343
=90.172483-1.562343
=88.61014 答案:arctan(0.77*13)+90-arctan(0.1*13)-arctan(0.01*13)-arctan(0.02*13)-arctan(13*9.1)=88.61014 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!
