I just joined the pro in order to see the step-by-step solution of a limit calculation. But after I became Pro and clicked on the step-by-step solution, the site gave me "Step-by-step solution unavailable." So, anyone knows what this means and how to deal with it? Thanks.
my query was "limit of ((1+a)(1+1/a)^(2a)-aexp(2))/(exp(2)-(1+1/a)^(2a)) as a goes to +?"
Back to "So, anyone knows what this means and how to deal with it?"
What it means is that Wolfram|Alpha does not know how to show steps for this example.
Teaching Wolfram|Alpha to show steps is an on-going project.
No space needed, Alpha interprets it as a multiplication in this instance.
I'm not saying that an explicit multiplication or a space would be a bad idea though.
Don't you need a multiplication sign between a and exp(2) ?
