Hi everybody, i have problems with solving these limits without using Lhopital's rule. Problems are in attachment.
I need to solve them without Lhopital's rule and Taylor expansion, becouse one of my friends has these problems during first semester of studying maths, and they don't know these technics yet. I solved couple of similar problems using the fact,
that if you have then you can substitute with when
and then calculate
. I can find these functions for
and but this doesn't help if i don't know these functions for
An alternative approach [I do hope it is 'allowed'...] to the second integral uses the 'infinite product'...
Setting in (1) and with a little computation we obtain...
... and from (2), taking into account the 'fundamental limit'...
... we obtain [finally!]...
