作业:求算式 180+arctan(11.3-0.442)-90-arctan(0.442)-arctan(0.25*0.442)-arctan(118.3*0.442) 的值.
题型:数学计算
解:
180+arctan(11.3-0.442)-90-arctan(0.442)-arctan(0.25*0.442)-arctan(118.3*0.442)
=180+arctan10.858-90-arctan(0.442)-arctan(0.25*0.442)-arctan(118.3*0.442)
=180+arctan10.858-90-arctan0.442-arctan(0.25*0.442)-arctan(118.3*0.442)
=180+arctan10.858-90-arctan0.442-arctan0.1105-arctan(118.3*0.442)
=180+arctan10.858-90-arctan0.442-arctan0.1105-arctan52.2886
=180+1.478957-90-arctan0.442-arctan0.1105-arctan52.2886
=180+1.478957-90-0.416181-arctan0.1105-arctan52.2886
=180+1.478957-90-0.416181-0.110054-arctan52.2886
=180+1.478957-90-0.416181-0.110054-1.551674
=181.478957-90-0.416181-0.110054-1.551674
=91.478957-0.416181-0.110054-1.551674
=91.062776-0.110054-1.551674
=90.952722-1.551674
=89.401048 答案:180+arctan(11.3-0.442)-90-arctan(0.442)-arctan(0.25*0.442)-arctan(118.3*0.442)=89.401048 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!
