sin theta+ cos theta cot theta = csc theta. Verify the trigonometric identity. {1 - sin theta} / {cos theta} = sec theta - tan theta Verify the trigonometric identity: sin theta tan theta + cos theta = sec theta. Verify the identity. cos (theta + 3 pi / 2) = sin theta Verify ...
(cos theta)/(sin(90^@ + theta)) + (sin(- theta))/(sin(180^@ + theta)) + (cot (90^@ + theta))/(tan theta) का मान बराबर है
Prove that:tan(900−θ)se(1800−θ)s∈(−θ)s∈(1800+θ)cot(3600−θ)cosec(900−θ)=1 If cot theta=-(7)/(24),(270^(@) Simplify (sin(180^(@)+theta)cos(360^(@)-theta)tan(270^(@)-theta))/(sec^(2)(90^(@)+theta)tan(-theta)sin(270^(@)+theta)) sin(180+θ...

x=r*cos(theta)+r*sin(theta)*theta*pi/180y=r*sin(theta)-r*cos(theta)*theta*pi/180z=0谁能解释下,为什么取theta=t*45,公式中t和45是怎么来的? 扫码下载作业帮搜索答疑一搜即得 答案解析 查看更多优质解析 解答一 举报 t是方程中自带的变量,值为0～1变化,至于45度,这个应该是控制图形在像限中的...
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 ...
