Hello "maxima people",
I was reding you since last couple of months; I'm a maxima enthusiast, even if I'm a maxima dummy!
Now back to the topic.
I tried all the operations appeared in this topic, and I reproduced all the expected outputs but one.
I wasn't able to make tlimit treat correctly the limit of h. tlimit only succedes treating h1, as proposed by
Richard Fateman: h1:radcan(h)
Here my session:
Do I use tlimit the wrong way?
Thank to all,
