Hello, I need to obtain Fourier Coefficients of a function, which I know come out in terms of Bessel functions. I tried following, but Mathematica simply returns me the input expression after trying to solve the expression. What am I doing wrong? I am new to mathematica. FourierCoefficient[E^(-I Sin[2 \[Pi] t]), t, n] FourierCoefficient[E^(-I Sin[2 \[Pi] t]), t, 1] FourierCoefficient[E^(-I Sin[2 \[Pi] t]), t, 2] Thanks Shalin website: http://mshalin.com (office) Lillie 110, (ph) 508-289-7374.
