Show that
∫∞−∞x2dx(x2+1)2(x2+2x+2)=7π50
So I figured since it's an improper integral I should change the limits
lim
I'm however not sure how to evaluate this. Any help would be great - thanks.
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}...
