Convert tanx into sinx/cosx. So, integration of (cosx+sinx/cosx / cosx-sinx/cosx) dx. Now remove cosx. So, integration of (cosx+sinx / cosx-sinx) dx. Let cosx+sinx=t, or, (-sinx+cosx) dx=dt. Now in the integration, put the above placements. So integration of (1/t) dt = log t. Put the value of t = cosx+sinx.
