I can't figure out why the following does not evaulate to TRUE:
In[100]:= \[ExponentialE]^(-\[ImaginaryI] x) + \[ExponentialE]^(\
\[ImaginaryI] x) == 2 TrigToExp[Cos[x]]
Out[100]= \[ExponentialE]^(-\[ImaginaryI] x) + \[ExponentialE]^(\
\[ImaginaryI] x) ==
2 (\[ExponentialE]^(-\[ImaginaryI] x)/
2 + \[ExponentialE]^(\[ImaginaryI] x)/2)
Any ideas?
