得出的角188.16968711°是正角度,比360°小,且与360+8.16968711+180共边。 θ=188.16968711° θ=188.16968711°θ=188.16968711° 求sin(θ)sin(θ)的周期。 点击获取更多步骤... 函数的周期可利用360|b|进行计算。 360|b| 使用周期公式中的1替换b。
首先,作为软件命令,首字母必须大写(如果命令有多个单词组成,每个单词的首字母大写)所以余弦函数应该是Cos,反余弦函数应该是ArcCos 另外,函数的参数要放在方括号里.在软件中,f(x)表示f乘x,f[x]才表示函数.Pi首字母大写 所以应该这样写:x=r*Cos[theta]+r*Sin[theta]*theta*Pi/180 ...
