☆算术计算1题
〖1/1算式〗
作业:求算式 -1*2*arctan1-arctan(0.2*3.717641)-arctan(0.0625*3.717641) 的值.
题型:数学计算
解:
-1*2*arctan1-arctan(0.2*3.717641)-arctan(0.0625*3.717641)
=-1*2*arctan1-arctan0.743528-arctan(0.0625*3.717641)
=-1*2*arctan1-arctan0.743528-arctan0.232353
=-1*2*0.785398-arctan0.743528-arctan0.232353
=-1*2*0.785398-0.639346-arctan0.232353
=-1*2*0.785398-0.639346-0.228302
=-2*0.785398-0.639346-0.228302
=(-1.570796)-0.639346-0.228302
=-2.210142-0.228302
=-2.438444 答案:-1*2*arctan1-arctan(0.2*3.717641)-arctan(0.0625*3.717641)=-2.438444 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!
