〖1/1算式〗
作业:求算式 -arctan(2.3/0.23)+arctan(2.3/0.0132)+arctan(2.3*0.25)+arctan(2.3*0.0625)-90+180 的值.
题型:数学计算
解:
-arctan(2.3/0.23)+arctan(2.3/0.0132)+arctan(2.3*0.25)+arctan(2.3*0.0625)-90+180
=-arctan10+arctan(2.3/0.0132)+arctan(2.3*0.25)+arctan(2.3*0.0625)-90+180
=-arctan10+arctan174.242424+arctan(2.3*0.25)+arctan(2.3*0.0625)-90+180
=-arctan10+arctan174.242424+arctan0.575+arctan(2.3*0.0625)-90+180
=-arctan10+arctan174.242424+arctan0.575+arctan0.14375-90+180
=-1.471128+arctan174.242424+arctan0.575+arctan0.14375-90+180
=-1.471128+1.565057+arctan0.575+arctan0.14375-90+180
=-1.471128+1.565057+0.521834+arctan0.14375-90+180
=-1.471128+1.565057+0.521834+0.142772-90+180
=0.093929+0.521834+0.142772-90+180
=0.615763+0.142772-90+180
=0.758535-90+180
=-89.241465+180
=90.758535 答案:-arctan(2.3/0.23)+arctan(2.3/0.0132)+arctan(2.3*0.25)+arctan(2.3*0.0625)-90+180=90.758535 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!
