    作业：求算式 arctan(22.41*0.51)-90-arctan(0.2*0.51)-arctan(0.5*0.51)-arctan(422.86*0.51) 的值.
    题型：数学计算
    解:
          arctan(22.41*0.51)-90-arctan(0.2*0.51)-arctan(0.5*0.51)-arctan(422.86*0.51)
        =arctan11.4291-90-arctan(0.2*0.51)-arctan(0.5*0.51)-arctan(422.86*0.51)
        =arctan11.4291-90-arctan0.102-arctan(0.5*0.51)-arctan(422.86*0.51)
        =arctan11.4291-90-arctan0.102-arctan0.255-arctan(422.86*0.51)
        =arctan11.4291-90-arctan0.102-arctan0.255-arctan215.6586
        =1.483523-90-arctan0.102-arctan0.255-arctan215.6586
        =1.483523-90-0.101648-arctan0.255-arctan215.6586
        =1.483523-90-0.101648-0.249679-arctan215.6586
        =1.483523-90-0.101648-0.249679-1.566159
        =-88.516477-0.101648-0.249679-1.566159
        =-88.618125-0.249679-1.566159
        =-88.867804-1.566159
        =-90.433963
    答案:arctan(22.41*0.51)-90-arctan(0.2*0.51)-arctan(0.5*0.51)-arctan(422.86*0.51)=-90.433963
