〖1/1算式〗
作业:求算式 2×arctan(0.5×3.5)-arctan0.035-arctan35-arctan(0.025×3.5) 的值.
题型:数学计算
解:
2×arctan(0.5×3.5)-arctan0.035-arctan35-arctan(0.025×3.5)
=2×arctan1.75-arctan0.035-arctan35-arctan(0.025×3.5)
=2×arctan1.75-arctan0.035-arctan35-arctan0.0875
=2×1.05165-arctan0.035-arctan35-arctan0.0875
=2×1.05165-0.034986-arctan35-arctan0.0875
=2×1.05165-0.034986-1.542233-arctan0.0875
=2×1.05165-0.034986-1.542233-0.087278
=2.1033-0.034986-1.542233-0.087278
=2.068314-1.542233-0.087278
=0.526081-0.087278
=0.438803 答案:2×arctan(0.5×3.5)-arctan0.035-arctan35-arctan(0.025×3.5)=0.438803 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!
