ABSTRACT
We have already encountered functional equations in Chapter 2. The methods mentioned there, however, are not suited to solve equations such as () f 2 ( t ) = 0 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003069577/5d33e1c8-4c4c-4f70-8923-318a0ea8baa8/content/eq903.tif"/> () f 2 ( t ) = t https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003069577/5d33e1c8-4c4c-4f70-8923-318a0ea8baa8/content/eq904.tif"/> () f ( 3 t ) = f ( t ) + t 2 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003069577/5d33e1c8-4c4c-4f70-8923-318a0ea8baa8/content/eq905.tif"/> () f ( t 2 − 2 f ( t ) ) = ( f ( t ) ) 2 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003069577/5d33e1c8-4c4c-4f70-8923-318a0ea8baa8/content/eq906.tif"/>
