July 16, 1987 Integration of Logs [Have TerminalIo viewer open]. Let's do an example that explores the behavior of the SMP integrator. Let me get myself a fresh CR tool. Let's enter an expression, differentiate it, and then integrate it to see if we get the same thing back.: First, the expression: X To differentiate, I wrap it with a differentiation template in the CaminoReal editor, and send it to SMP: X which gives: X Now I wrap this with an integration template, and pass to SMP, which gives: X Now we want to try a trigonometric substitituion. I make the SMP command by wrapping a function template: X into the previous expression which gives the expression X X not to be shown
