〖1/1算式〗
作业:求算式 arctan(0.33×5.93)-arctan(0.5×5.93)-arctan(0.1×5.93)-arctan(0.033×5.93) 的值.
题型:数学计算
解:
arctan(0.33×5.93)-arctan(0.5×5.93)-arctan(0.1×5.93)-arctan(0.033×5.93)
=arctan1.9569-arctan(0.5×5.93)-arctan(0.1×5.93)-arctan(0.033×5.93)
=arctan1.9569-arctan2.965-arctan(0.1×5.93)-arctan(0.033×5.93)
=arctan1.9569-arctan2.965-arctan0.593-arctan(0.033×5.93)
=arctan1.9569-arctan2.965-arctan0.593-arctan0.19569
=1.098378-arctan2.965-arctan0.593-arctan0.19569
=1.098378-1.245509-arctan0.593-arctan0.19569
=1.098378-1.245509-0.535257-arctan0.19569
=1.098378-1.245509-0.535257-0.193248
=-0.147131-0.535257-0.193248
=-0.682388-0.193248
=-0.875636 答案:arctan(0.33×5.93)-arctan(0.5×5.93)-arctan(0.1×5.93)-arctan(0.033×5.93)=-0.875636 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!
