For ( )=2V (A0 ( frac {1+cos theta }{sin theta } ) + (_{n=1}^ )sin n An) select the statement which is invalid.

The solution is valid for all thin airfoils

The solution is valid only for cambered airfoils

The solution is valid for all thin airfoils

A0 Is the n=0th term for the Fourier series

Kutta condition is satisfied at the trailing edge i.e. = .
