更新以后空历被打坏了会有弃机倒计时吗？ rt，刚才楼主用鸢种开线被打掉左侧机翼一半，结果跳出来弃机倒计时15s
我宣布，你游陆战开线非常之高血压 rt，之前经常帮别人打空战，平均一个小时八九万研发，这几天试着打陆战研发，不仅高血压收益还低，陆战应该多少分挂机呢
拼多多今天多打的时长到第二天还能发箱子不现在？ 我记得之前的拼多多前一天多肝的时间到第二天会补发箱子这次拼多多可以吗
游戏里j8的平尾方向是不是反了？ 就感觉拉杆和压杆的时候平尾不应该像游戏那样动才对啊
FindRoot问题 R = 100.0; a = 5.0; r = Sqrt[a (2*R - a)]; n1 = n3 = 1; n2 = 1.52; light = {}; \[Theta] = 0 \[Degree]; Do[ p1 = {-0.5 *R, y0}; k = n1*{Cos[\[Theta]], -Sin[\[Theta]]}; s = FindRoot[{k[[1]]*(y - p1[[2]]) == k[[2]] *(x - p1[[1]]), R^2 - (y^2 + (x - R + a)^2) == 0}, {{x, -a}, {y, y0}}]； p2 = {x, y} /. s; f = R^2 - (y^2 + (x - R + a)^2); \[CapitalOmega] = D[f, {{x, y}}] /.

请教大佬们这个问题是啥啊 n0 = 1.1; \[Alpha] = 0.5*10^-3; \[Theta] = \[Pi]/4; n[y_] := n0 - \[Alpha]y; sm = 3*10^3; equ = {D[n[y[s]]*y'[s], s] == -\[Alpha], D[n[y[s]]*z'[s], s] == 0, y[0] == 0, y'[0] == Sin [\[Theta]], z[0] == 0, z'[0] == Cos[\[Theta]]}; sol = NDSolve[equ, {z, y}, {s, 0, sm}] ParametricPlot [{z[s] y[s]} /. sol[[1]], {s, 0, sm}, AxesLabel \[RightArrow] {"Z", "Y"}] Clear ["Global`*"]
