Question

Solve integral

Answer 1

\[\int\limits (x-\sqrt (\arctan2x) )/(1+4x^2)dx\]

Answer 2

@soati : how about this?

Answer 3

tha arctan2x=t...
\[\tan^{-1} 2x=t\]
\[\frac{dx}{1+4x^{2}}=dt\]

Answer 4

can you solve it....can you solve it??
if not ask me

Answer 5

\[\tan^{-1} 2x=t\]
\[2x=\tan t\]
\[x=\frac{1}{2} tant\]

Answer 6
