7. Transform Methods

7-1 Fourier Transforms The Fourier transform F(λ) of a function ƒ(t) is defined by F (λ) = 1 2π ∫ −∞ ∞ eiλτ ƒ (τ) dτ It is of great value in the treatment of many problems involving differential or integral equations. Intrinsically, F(λ) is an analytic function of the complex variable λ, and this fa... View More
