Answer

\(\boxed{\cot \theta = \frac{5}{12}}\)

Steps

Step 1 :\(\tan \theta = \frac{\sin \theta}{\cos \theta}\)

Step 2 :Substitute \(\sin \theta = \frac{12}{13}\) and \(\cos \theta = \frac{5}{13}\) into the equation

Step 3 :\(\tan \theta = \frac{\frac{12}{13}}{\frac{5}{13}} = \frac{12}{5}\)

Step 4 :\(\boxed{\tan \theta = \frac{12}{5}}\)

Step 5 :\(\csc \theta = \frac{1}{\sin \theta}\)

Step 6 :Substitute \(\sin \theta = \frac{12}{13}\) into the equation

Step 7 :\(\csc \theta = \frac{1}{\frac{12}{13}} = \frac{13}{12}\)

Step 8 :\(\boxed{\csc \theta = \frac{13}{12}}\)

Step 9 :\(\sec \theta = \frac{1}{\cos \theta}\)

Step 10 :Substitute \(\cos \theta = \frac{5}{13}\) into the equation

Step 11 :\(\sec \theta = \frac{1}{\frac{5}{13}} = \frac{13}{5}\)

Step 12 :\(\boxed{\sec \theta = \frac{13}{5}}\)

Step 13 :\(\cot \theta = \frac{1}{\tan \theta}\)

Step 14 :Substitute \(\tan \theta = \frac{12}{5}\) into the equation

Step 15 :\(\cot \theta = \frac{1}{\frac{12}{5}} = \frac{5}{12}\)

Step 16 :\(\boxed{\cot \theta = \frac{5}{12}}\)
