Solution

Step 1 :Given that \(\sin \theta = \frac{3 \sqrt{10}}{10}\) and \(\cos \theta = -\frac{\sqrt{10}}{10}\)

Step 2 :We can calculate the other trigonometric functions using these values.

Step 3 :The tangent of an angle is the sine of the angle divided by the cosine of the angle, so \(\tan \theta = \frac{\sin \theta}{\cos \theta} = -3\)

Step 4 :The cotangent is the reciprocal of the tangent, so \(\cot \theta = \frac{1}{\tan \theta} = -\frac{1}{3}\)

Step 5 :The cosecant is the reciprocal of the sine, so \(\csc \theta = \frac{1}{\sin \theta} = \frac{\sqrt{10}}{3}\)

Step 6 :The secant is the reciprocal of the cosine, so \(\sec \theta = \frac{1}{\cos \theta} = -\sqrt{10}\)

Step 7 :Final Answer: \(\tan \theta = \boxed{-3}\), \(\cot \theta = \boxed{-\frac{1}{3}}\), \(\csc \theta = \boxed{\frac{\sqrt{10}}{3}}\), \(\sec \theta = \boxed{-\sqrt{10}}\)
