〖1/1算式〗
作业:求算式 arctan(0.133*55.97*0.56)-90-arctan(0.56)-arctan(0.5*0.56) 的值.
题型:数学计算
解:
arctan(0.133*55.97*0.56)-90-arctan(0.56)-arctan(0.5*0.56)
=arctan4.168646-90-arctan(0.56)-arctan(0.5*0.56)
=arctan4.168646-90-arctan0.56-arctan(0.5*0.56)
=arctan4.168646-90-arctan0.56-arctan0.28
=1.335359-90-arctan0.56-arctan0.28
=1.335359-90-0.510488-arctan0.28
=1.335359-90-0.510488-0.273009
=-88.664641-0.510488-0.273009
=-89.175129-0.273009
=-89.448138 答案:arctan(0.133*55.97*0.56)-90-arctan(0.56)-arctan(0.5*0.56)=-89.448138 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!
