I am trying to NIntegrate the function HypergeometricU[a,b,z] with
a>=1, b>=1,z=R/sin[x]^2 where integration is from 0 to Pi/2. For lower
values of R this gives answers and for Higher values of R this is
giving errors .
\!\(NIntegrate::"singd" \(\(:\)\(\ \)\) "NIntegrate's singularity
handling
has failed at point \
\!\({x}\)=\!\({8.145014137541`5.15492657977389*^-15}\) for the
specified \
precision goal. Try using larger values for any of $MaxExtraPrecision
or the \
options WorkingPrecision, or SingularityDepth and MaxRecursion"\)
Even though I change the working precisio,SingularityDepth and
MaxRecursion it is not helping me much. Please advice me how to solve
this problem.
