〖1/1算式〗
作业:求算式 180+arctan(3*0.229)-90-arctan(6*0.229)-arctan(100*0.229/623.689)-arctan(10*0.229) 的值.
题型:数学计算
解:
180+arctan(3*0.229)-90-arctan(6*0.229)-arctan(100*0.229/623.689)-arctan(10*0.229)
=180+arctan0.687-90-arctan(6*0.229)-arctan(100*0.229/623.689)-arctan(10*0.229)
=180+arctan0.687-90-arctan1.374-arctan(100*0.229/623.689)-arctan(10*0.229)
=180+arctan0.687-90-arctan1.374-arctan0.036717-arctan(10*0.229)
=180+arctan0.687-90-arctan1.374-arctan0.036717-arctan2.29
=180+0.601948-90-arctan1.374-arctan0.036717-arctan2.29
=180+0.601948-90-0.941654-arctan0.036717-arctan2.29
=180+0.601948-90-0.941654-0.036701-arctan2.29
=180+0.601948-90-0.941654-0.036701-1.159073
=180.601948-90-0.941654-0.036701-1.159073
=90.601948-0.941654-0.036701-1.159073
=89.660294-0.036701-1.159073
=89.623593-1.159073
=88.46452 答案:180+arctan(3*0.229)-90-arctan(6*0.229)-arctan(100*0.229/623.689)-arctan(10*0.229)=88.46452 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!
