〖1/1算式〗
作业:求算式 400*(0.048-0.01*(1+sin25.3))*0.005*cos(24.7-5)/sin25.3*cos45 的值.
题型:数学计算
解:
400*(0.048-0.01*(1+sin25.3))*0.005*cos(24.7-5)/sin25.3*cos45
=400*(0.048-0.01*1.16648)*0.005*cos(24.7-5)/sin25.3*cos45
=400*0.036335*0.005*cos(24.7-5)/sin25.3*cos45
=400*0.036335*0.005*cos19.7/sin25.3*cos45
=400*0.036335*0.005*0.659649/sin25.3*cos45
=400*0.036335*0.005*0.659649/0.16648*cos45
=400*0.036335*0.005*0.659649/0.16648*0.525322
=14.534*0.005*0.659649/0.16648*0.525322
=0.07267*0.659649/0.16648*0.525322
=0.047937/0.16648*0.525322
=0.287944*0.525322
=0.151263 答案:400*(0.048-0.01*(1+sin25.3))*0.005*cos(24.7-5)/sin25.3*cos45=0.151263 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!
