tanx=t^2 so sec^2xdx=2tdt so dx=2tdt/1+t^4
so we have integral{  t* 2tdt/1+t^4}
afterthis

Put\;\tan{x}=t^{2}\\\\
u\;get\\\\
\int{\frac{2t^{2}}{1+t^{4}}}dt\\\\
\int{\frac{t^{2}+1+t^{2}-1}{1+t^{4}}}dt\\\\
\int{\frac{1+t^{2}}{1+t^{4}}}+\int{\frac{t^{2}-1}{1+t^{4}}}\\\\
\int{\frac{(1+\frac{1}{t^{2}})}{(t-\frac{1}{t})^{2}+(\sqrt{2})^{2}}}+\int{\frac{1-\frac{1}{t^{2}}}{(t+\frac{1}{t})^{2}}-2}\\\\
Now\\\\
Put\;t-\frac{1}{t}=u\;in\;the\;first\;one\\\\
Put\;t+\frac{1}{t}=v\;in\;the\;second\;one\\\\
rest\;is\;simple
