Help me please with this improper integral:
∫∞0e−√xdx
Thanks.
I solved it partially, and stuck after integration by parts.
Answer
I=lim
The last limit can be evaluated using substitution t=\sqrt{a}~ and L'Hopital rule .
How to find \lim_{h\rightarrow 0}\frac{\sin(ha)}{h} without lhopital rule? I know when I use lhopital I easy get $$ \lim_{h\rightarrow 0}...
