Question

calcular tgx+1 sobre ctgx+1

Answer 1

${\frac{tanx+1}{ctgx+1}=}\\\\{\frac{\frac{senx}{cosx}+1}{\frac{cosx}{senx}+1}=}\\\\{\frac{\frac{senx+cosx}{cosx}}{\frac{cosx+senx}{senx}}=}\\\\{\frac{senx+cosx}{cosx} \times \frac{senx}{senx+cosx}=}\\\\{\frac{senx}{cosx}=}\\\\{\boxed{tanx}}\\\\{\mathbf{salu2.!!\ :)}}\\{\mathbf{Wellington}}$
