〖1/1算式〗
作业:求算式 arctan(0.49*103.34*0.112)-90-arctan(0.49)-arctan(0.5*0.49) 的值.
题型:数学计算
解:
arctan(0.49*103.34*0.112)-90-arctan(0.49)-arctan(0.5*0.49)
=arctan5.671299-90-arctan(0.49)-arctan(0.5*0.49)
=arctan5.671299-90-arctan0.49-arctan(0.5*0.49)
=arctan5.671299-90-arctan0.49-arctan0.245
=1.396264-90-arctan0.49-arctan0.245
=1.396264-90-0.455616-arctan0.245
=1.396264-90-0.455616-0.240267
=-88.603736-0.455616-0.240267
=-89.059352-0.240267
=-89.299619 答案:arctan(0.49*103.34*0.112)-90-arctan(0.49)-arctan(0.5*0.49)=-89.299619 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!
