➪ \frac{ \sin  \theta}{1 -  \frac{cos  \theta}{sin  \theta} }  +  \frac{cos  \theta}{1 -  \frac{sin  \theta}{cos  \theta} }

➪\frac{ \sin  \theta}{   \frac{sin \theta - cos  \theta}{sin  \theta} }  +  \frac{cos  \theta}{ \frac{cos \theta \:  - sin  \theta}{cos  \theta} }

➪  \frac{sin ^{2}\theta}{sin\theta \:  - cos\theta}  -  \frac{cos^{2}\theta}{sin\theta \:  - cos\theta}

➪ \frac{ \: sin^{2}\theta -cos^{2}\theta }{sin\theta \:  - cos\theta}

➪sin\theta + cos\theta
