The integrodifferential equation describing the linear tearing instability in the bi-Maxwellian neutral sheet is solved without approximating the particle orbits or the eigenfunction /psi/. Results of this calculation are presented. Comparison between the exact solution and the three-region approximation (Phys. Fluids /bold 27/, 1198 (1984)) motivates the piecewise-straight-line approximation, a simplification that allows faster solution of the integrodifferential equation, yet retains the important features of the exact solution.
