func VerticalRisePerBond() float64 · AdjacentBondLength returns L_adj

Read the equation

This relation defines AdjacentBondLength returns L_adj in the source section “func VerticalRisePerBond() float64 · AdjacentBondLength returns L_adj”. Evaluates oscillatory sine or cosine terms using the stated phase or frequency. Takes a square root, requiring a nonnegative real radicand when interpreted over the reals. Its interpretation depends on the source’s stated variables and conditions; this record does not assign an unprovided physical or cognitive meaning to them.

Original context

}

// VerticalRisePerBond returns Δz_bond = P/44 = 0.0819 nm
func VerticalRisePerBond() float64 {
	return Pitch / TotalBonds
}

// AdjacentBondLength returns L_adj = √[2r²(1 - cos(2π/10.6)) + h²] = 0.54 nm
func AdjacentBondLength() float64 {
	cosTerm := 1.0 - math.Cos(TwistAngleRad)
	return math.Sqrt(2.0*HelixRadius*HelixRadius*cosTerm + RisePerBP*RisePerBP)
}

// UpdateBonds updates all bond states at given theta
func (bs *BondSystem44) UpdateBonds(theta float64) {
	for i := range bs.Bonds {
		bs.Bonds[i].Length = bs.Bonds[i].CalculateLength(theta)
	}

AdjacentBondLength returns L_adj = √[2r²(1 - cos(2π/10.6)) + h²] = 0.54 nm
