Question

{
{b = 10.62
A1 = 25.63112
A2 = 25.17559
a1 = 1.149626
a2 = 1.182199
A = A1 - A2
a = a1 - a2
Solve[{ArcTan[
sin[t Degree]/(sin[c Degree]*cos[t Degree] -
cos[c Degree]*tan[b Degree])] -
ArcTan[sin[(t + 0.75) Degree]/(sin[c Degree]*cos[t Degree] -
cos[c Degree]*tan[b Degree])] - A == 0,
1/((sin[b Degree]*sin[c Degree] +
cos[c Degree]*cos[b Degree]*cos (t Degree))^2) -
a/((sin[b Degree]*sin[c Degree] +
cos[c Degree]*cos[b Degree]*cos ((t + 0.75) Degree))^2) -
1 + a == 0}, {c, t}]
}

运行以后，什么都不会跳出来

Answer 1

你的式子里面错误太多，比如说 Sin和Cos要大写。。。还有cos ((t + 0.75) Degree)) 部位应该写成Cos [(t + 0.75) Degree)] 等等。。你最好是仔细再检查一遍。
