本世纪最难的三角函数题
tanX ÷tan(45-X) =1.5
tanX ÷tan(45-X) =1.5
In[1]:= Solve[Tan[x]/Tan[\[Pi]/4 - x] == 1.5, x]
During evaluation of In[1]:= Solve::ifun: Inverse functions are being used by Solve, so some solutions may not be found; use Reduce for complete solution information. >>
Out[1]= {{x -> -2.67795}, {x -> -1.24905}, {x -> 0.463648}, {x ->
1.89255}}
用数学软件解的,出来这么个东西
