Read the equation
This relation defines InterStrandEnergy: E_inter(k, k+1) in the source section “func (be *BondEnergy) IntraStrandEnergy(Lk float64) float64 · InterStrandEnergy: E_inter(k, k+1)”. Evaluates oscillatory sine or cosine terms using the stated phase or frequency. Its interpretation depends on the source’s stated variables and conditions; this record does not assign an unprovided physical or cognitive meaning to them.
Terms & definitions
The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.
How it works
