Why no SOLVE & INTEGRATE commands on the 41C?

Maybe because HP wanted to sell expensive software modules together with their calculators? Around the time when the HP-41 was on the market, the letters "HP" were an acronym for "high price", at least in my part of the word. Ultimately this is the reason why they lost the education market to the competition.

The code for a root finder was provided in the Standard Applications booklet which came with the HP-41C. And examples of code for solving integrals using Simpson's Rule or similar methods were easy to find, including HP literature (i.e.: HP 25 Applications Manual), so the code and methods were readily available for anyone interested in such problems. The Application Pacs modules were a separate product indeed, but I don't think HP decided to drive their sales by reducing the native HP-41C function set, which was extensive and complete at the time. Just my opinion,
