If\[\frac{ d }{ dx }\frac{ 5x }{ (2x+1) }=\frac{ 5 }{ (2x+1)^2 }\],
OpenStudy (anonymous):
find\[\int\limits_{}^{}\frac{ 1 }{ (2x+1)^2 }dx\]
hartnn (hartnn):
so, did you get x/(2x+1) ?
OpenStudy (anonymous):
yes
hartnn (hartnn):
this one was easier then previous ones :P

okay, lol
But,thank you @hartnn\[\huge{:)}\]
hartnn (hartnn):
wait, are you sure you calculated derivative correctly?
OpenStudy (anonymous):
do u want to c my working..maybe u can check it
hartnn (hartnn):
the final answer should have been -1/[2(2x+1)]
hartnn (hartnn):
yes please

okay

This is my working..\[\int\limits_{}^{}\frac{ 5 }{ (2x+1)^2 }dx=\frac{ 5x }{ 2x+1 }\]\[5\int\limits_{}^{}\frac{ 1 }{ (2x+1)^2 }dx=\frac{ 5x }{ 2x+1 }\]\[\int\limits_{}^{}\frac{ 1 }{ (2x+1)^2 }dx=\frac{ 1 }{ 5 }(\frac{ 5x }{ 2x+1 })\]\[=\frac{ x }{ 2x+1 }\]
hartnn (hartnn):
ok, yes its correct!
seems that this x/(2x+1) is just another equivalent answer!

Thank you @hartnn\[\huge{:)}\]
