( tan theta=frac{sin alpha+cos alpha}{sin alpha-cos alpha} ) ( Rightarrow operatorname{dan} theta=frac{sin alpha}{sin alpha}+alpha+1 ) ( tan theta=frac{operatorname{sen} alpha+1}{tan alpha-1} ) ( Rightarrow tan (tan alpha-1)=operatorname{san} alpha+1 ) 2) tand bend - tan ( theta=tan alpha+1 ) ( Rightarrow quad tan A t ) ( Rightarrow operatorname{san} alpha(operatorname{san} theta-1)=1+operatorname{sen} theta ) ( Rightarrow tan alpha=frac{tan theta+1}{tan theta-1} ) s) ( tan alpha=frac{frac{sin theta}{cos theta}+1}{frac{sin theta}{cos theta}-1} ) ( Rightarrow ) ben ( alpha=frac{sin theta+cos theta}{sin theta-cos theta} )
