I like writing integrals symbolically instead of using Integrate. I suddenly seem to not be able to do this and am confused. I type
\[Esc] int \[Esc] then
\[Ctrl] + _ for my lower bound, and online it says use
\[Ctrl] + % for the upper bound, but nothing happens. I've also tried using
\[Ctrl] + ^ which here says it is a superscript, and that gets me somewhere. However, I get a syntax error.
So for the
\[Ctrl] + ^ case, I'm typing
\[Esc]int\[Esc]\[Ctrl]+_0\[rightarrow]\[Ctrl]+^1 2 \[Esc]dd\[Esc]x and I get the syntax error
Syntax::sntxi: Incomplete expression; more input is needed .
I've also tried putting parenthesis around the integrand, but it doesn't help. On the screen it looks fine:
So why doesn't the
\[Ctrl] + % do anything? And ultimately, how do I get this symbolic integral to evaluate? Thanks for the help.
