comment How can this type of optical illusion be created in Mathematica?
@RHall He used ComplexExpand to simply justify to the formula he is using inside the ImageForwardTransformation.

you can simply do expr/.Gamma[n+1/2]-> Sqrt[Pi](2 n-1)!!/2^n and check!

comment Limitations of ParametricNDSolve family w.r.t objective functions
@ruebenko Sorry! I expect -7.86673 for pfun[1.5]. I had a mistake in the previous comment.

comment Limitations of ParametricNDSolve family w.r.t objective functions
@ruebenko if pfun[1.5] is unevaluated and so is pfun'[1.5] then one needs to be really audacious to expect even anything sensible for the higher derivatives. But M9 in this specific case returns values for the higher derivatives. That is not the kind of behavior one expects from a intelligent system.

comment How to nest the output of FindRoot in a table of Derivative evaluations?
I can not comment on this issue until I see the larger system. However my approach should work seamlessly as far as mathematics is concerned.

@cormullion you had already done that nicely when I saw this question so I thought to add little randomness to the set of answers...;)
