For some functions, EXPAN must be used repeatedly, until the function is fully expanded. The COLCT function must then be used to compact the function into a useable form (read collect like terms). I have found however, that this calculator's indefinite integral (symbolic integral) function is very fussy about giving answers for even some of the built in functions, which the manual says it should be able to integrate. Dissapointing, but true. If you have any further problems, or if I didn't answer your question please write again! Ross A Bagley | | | Univ | | of |_____ \____/ | Cinci \______ rbagley@uceng.uc.edu
