# Errata for Theory of Lift

§2.5.1
dynamic pressure ρq²c/2’ → ‘dynamic pressure ρq²/2 and the chord c
§3.5.4
Γ = 2πiA−1’ → ‘Γ = 2πℑA−1
§4.1
‘It follows that z(C) is a streamline in the ζ-plane.’ → ‘It follows that z(C) is a streamline in the z-plane.’
Listing 4.2
The fourth argument should be ‘`@ (Z) 2.^2`’.
§4.4.2 (f)
‘modiy’ → ‘modify’
‘that internal’ → ‘that the internal’
§5.3
In the second formula for ml.e., the third and final R.H.S. needs to be multiplied by π
Figure 6.1, caption
‘Rrelative’ → ‘Relative’
Figure 6.2, caption
‘Relative’ → ‘Reduced’ (for consistency with Figure 6.1)
Listing 7.5
Insert ‘```z = complex (x, y');``` after l. 2
Then in last line ‘`zc`’ → ‘`zc + diff (z.') / 2`
§7.5.2
‘−0.059078’ → ‘−0.0536’
‘is less good, but still reasonable’ → ‘is also reasonable’
§7.7.6
‘(11.11)’ → ‘(5.3b)’
§8.1.1, ‘Conformal Mapping for Arbitrary Segments’
In first expression for ζ: ‘z1’ → ‘z2’, ‘z0’ → ‘z1
§8.3, ‘References’
full-stop misplaced
§10.4.2
‘the choice of r, consider’ → ‘the choice of r′, consider’
§10.6.2
Γ’ →‘−Γ’ on the R.H.S. of the formula
§11.4.2, ‘Lift’
In the third R. H. S., ‘dθ’ → ‘sin θ dθ
§13.2.1
‘back from’ → ‘to’
Listing 14.4
Delete first definition of `r1`
Figure 14.2, caption
‘=5’ → ‘=6’
(15.2)
‘−∇P’ → ‘∇⋅σ
§16.3.3, ‘Example: Error Function Profile’
The momentum thickness for the error function profile can be evaluated analytically too: it's (√2 − 1) / √π.
§16.4.4
Double first expression on R.H.S. by 2, and also the second term of the second expression.

Thanks to Matthew Silic for spotting some of these errors.
