Quick derivation question Quantum Mechanics

Click For Summary
SUMMARY

The discussion centers on a derivation question in Quantum Mechanics, specifically regarding the transition from initial expressions to two circled terms in a given equation. Participants suggest that multiplying both sides of the equation by iħ (where i is the imaginary unit and ħ is the reduced Planck constant) is a crucial step in the derivation process. The conversation highlights the common struggle with understanding complex derivations in Quantum Mechanics and emphasizes the importance of clear mathematical manipulation.

PREREQUISITES
  • Understanding of Quantum Mechanics principles
  • Familiarity with complex numbers and the imaginary unit (i)
  • Knowledge of the reduced Planck constant (ħ)
  • Basic skills in algebraic manipulation of equations
NEXT STEPS
  • Study the role of iħ in Quantum Mechanics equations
  • Review derivations of fundamental Quantum Mechanics equations
  • Learn about the implications of multiplying equations by constants in Quantum Mechanics
  • Explore common pitfalls in Quantum Mechanics derivations and how to avoid them
USEFUL FOR

Students of Quantum Mechanics, educators teaching advanced physics concepts, and anyone seeking to improve their understanding of mathematical derivations in Quantum Mechanics.

Homework Statement


Having one of those days where nothing makes sense, here is the derivation:

how does he get the two circled terms from what he's derived above?

The Attempt at a Solution


I tried substitution but get nowhere I just can't see how the early expressions help in getting the circled expressions.

once again, any pointers in the right direction would be appreciated

Er...isn't it just a matter of multiplying both sides by i \hbar?
