Vector Calculation Derivation

// 1. Polar to Complex Vector Conversion

O = --

O+T = --

Trial Weight Vector (W_trial) = --

// 2. Trial Effect Vector (T = (O+T) - O)

T = --

T (Polar) = --

// 3. Influence Coefficient (α = T / W_trial)

α = --

α (Polar) = --

// 4. Ideal Correction Weight (W_exact = -O / α)

W_exact = --

// 5. Discrete Blade Vector Resolution (Direction Aware)

Target Angle (θ_target) = --

Adjacent Blade A (#-- at --°): W_A = --

Adjacent Blade B (#-- at --°): W_B = --
