Physics 6810: Assignment #1b

Bessel Function Recursing Up and Down

• You will just be modifying a code from Activites 2; you don't need to write one from scratch.
• The interpretation of the graph should explain the meaning of the regions where the plotted error is about unity and where it is very small. (I.e., which result is good and which is poor, or are both good or poor? And what is the significance of the very small value?) If you can explain the values of the slopes in the intermediate regions that is great, but don't worry if you can't (yet!). However, you should report the slopes and say what they mean for the dependence of the error on x.
• For part c), remember that you need the linker option -lgsl -lgslcblas in your makefile to run a program that uses the GSL library. Don't forget that you need to #include a GSL header file (see the Bessel function example from Activities 1).
