Different forms of Schrodinger equation

Click For Summary
SUMMARY

The discussion revolves around the transition between different forms of the Schrödinger equation in quantum mechanics. The user expresses confusion regarding the algebraic manipulation of the equations, particularly in relation to complex numbers. They highlight that the last equation in one representation is derived from another by multiplying by \(-\frac{i}{\hbar}\), clarifying the relationship between the two forms. This exchange emphasizes the importance of understanding complex number operations in quantum mechanics.

I got confused when in my book they went from one form of Schrödinger equation to another. It doesn't make much sense to me algebraically, probably i have some lacks in complex numbers. Here are the equations:

In the second one I think it's implied that above two equations give third and I am not sure how.
 
Physics news on Phys.org
The last equation of the second picture is the same as the equation in the other picture, just multiplied by ##\frac{-i}{\hbar}## (note that -i * i = 1)
 
Thanks I completely forgot about it haha
