作业:求算式 arctan(0.77*3)+arctan(3.33*3)-arctan(0.144*3)-arctan(0.1*3)-arctan(3)-arctan(36.67*3)-90 的值.
题型:数学计算
解:
arctan(0.77*3)+arctan(3.33*3)-arctan(0.144*3)-arctan(0.1*3)-arctan(3)-arctan(36.67*3)-90
=arctan2.31+arctan(3.33*3)-arctan(0.144*3)-arctan(0.1*3)-arctan(3)-arctan(36.67*3)-90
=arctan2.31+arctan9.99-arctan(0.144*3)-arctan(0.1*3)-arctan(3)-arctan(36.67*3)-90
=arctan2.31+arctan9.99-arctan0.432-arctan(0.1*3)-arctan(3)-arctan(36.67*3)-90
=arctan2.31+arctan9.99-arctan0.432-arctan0.3-arctan(3)-arctan(36.67*3)-90
=arctan2.31+arctan9.99-arctan0.432-arctan0.3-arctan3-arctan(36.67*3)-90
=arctan2.31+arctan9.99-arctan0.432-arctan0.3-arctan3-arctan110.01-90
=1.162253+arctan9.99-arctan0.432-arctan0.3-arctan3-arctan110.01-90
=1.162253+1.471029-arctan0.432-arctan0.3-arctan3-arctan110.01-90
=1.162253+1.471029-0.407785-arctan0.3-arctan3-arctan110.01-90
=1.162253+1.471029-0.407785-0.291457-arctan3-arctan110.01-90
=1.162253+1.471029-0.407785-0.291457-1.249046-arctan110.01-90
=1.162253+1.471029-0.407785-0.291457-1.249046-1.561706-90
=2.633282-0.407785-0.291457-1.249046-1.561706-90
=2.225497-0.291457-1.249046-1.561706-90
=1.93404-1.249046-1.561706-90
=0.684994-1.561706-90
=-0.876712-90
=-90.876712 答案:arctan(0.77*3)+arctan(3.33*3)-arctan(0.144*3)-arctan(0.1*3)-arctan(3)-arctan(36.67*3)-90=-90.876712 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!
