ABSTRACT
In the previous chapter the time independent consideration of Green’s functions for dealing with source terms in differential equations was covered as well as sinusoidal driving and response time dependency. Recall, the partial differential equations ∇ 2 ψ = − 4 π ρ , https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003037460/09a5fcca-c56a-4e61-b8a6-98aae4c87b83/content/eqn9_1.tif"/> ∇ 2 ψ − 1 k ∂ ψ ∂ t = − 4 π ρ , https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003037460/09a5fcca-c56a-4e61-b8a6-98aae4c87b83/content/eqn9_2.tif"/> ∇ 2 ψ − 1 c 2 ∂ 2 ψ ∂ t 2 = − 4 π ρ , https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003037460/09a5fcca-c56a-4e61-b8a6-98aae4c87b83/content/eqn9_3.tif"/>
