the guy present a function like this :

ψ = A cos(x)

then he says according to Euler formula, which is e^ix = cos(x) + i sin(x) :

ψ = A e^ix ??

shouldn't the result be instead :

ψ + A*i*sin(x) = A cos(x) + A*i* sin(x)

ψ + A*i*sin(x) = A (cos(x) + i sin(x))

ψ = A e^ix - A*i*sin(x)

ψ = A (e^ix - i sin(x))
