$\\tan\:75^{\circ}+cot\:75^{\circ}=\frac{sin\:75^{\circ}}{cos\:75^{\circ}}+\frac{cos\:75^{\circ}}{sin\:75^{\circ}}=\frac{sin^2\:75^{\circ}+cos^2\:75^{\circ}}{sin\:75^{\circ}\cdot cos\:75^{\circ}}\\=\frac{2}{2\cdot sin\:75^{\circ}\cdot cos\:75^{\circ}}=\frac{2}{sin\:150^{\circ}}=\frac{2}{sin\:30^{\circ}}=\frac{2}{\frac{1}{2}}=\cdots$
