Solution Steps

To find the exact value of the remaining five trigonometric functions given \(\tan \theta = \sqrt{29}\), we can use the following steps:

  1. Use the definition of \(\tan \theta\) to find \(\sin \theta\) and \(\cos \theta\).
  2. Use the Pythagorean identity to find \(\sin \theta\) and \(\cos \theta\).
  3. Calculate \(\csc \theta\), \(\sec \theta\), and \(\cot \theta\) using the reciprocal identities.
Solution Approach
  1. Given \(\tan \theta = \sqrt{29}\), we know \(\tan \theta = \frac{\sin \theta}{\cos \theta}\).
  2. Assume \(\sin \theta = \sqrt{29} \cos \theta\).
  3. Use the Pythagorean identity: \(\sin^2 \theta + \cos^2 \theta = 1\).
  4. Solve for \(\cos \theta\) and then find \(\sin \theta\).
  5. Use the reciprocal identities to find \(\csc \theta\), \(\sec \theta\), and \(\cot \theta\).
Step 1: Given Information

We are given that \(\tan \theta = \sqrt{29}\).

Step 2: Express \(\sin \theta\) in terms of \(\cos \theta\)

Using the definition of tangent, we have: \[ \tan \theta = \frac{\sin \theta}{\cos \theta} \implies \sin \theta = \sqrt{29} \cos \theta \]

Step 3: Use the Pythagorean Identity

Using the Pythagorean identity: \[ \sin^2 \theta + \cos^2 \theta = 1 \] Substitute \(\sin \theta = \sqrt{29} \cos \theta\): \[ (\sqrt{29} \cos \theta)^2 + \cos \theta^2 = 1 \implies 29 \cos^2 \theta + \cos^2 \theta = 1 \implies 30 \cos^2 \theta = 1 \implies \cos^2 \theta = \frac{1}{30} \] Thus: \[ \cos \theta = \frac{\sqrt{30}}{30} \]

Step 4: Calculate \(\sin \theta\)

Using \(\sin \theta = \sqrt{29} \cos \theta\): \[ \sin \theta = \sqrt{29} \cdot \frac{\sqrt{30}}{30} = \frac{\sqrt{870}}{30} \]

Step 5: Calculate the Remaining Trigonometric Functions

Using the reciprocal identities: \[ \csc \theta = \frac{1}{\sin \theta} = \frac{30}{\sqrt{870}} = \frac{\sqrt{870}}{29} \] \[ \sec \theta = \frac{1}{\cos \theta} = \frac{30}{\sqrt{30}} = \sqrt{30} \] \[ \cot \theta = \frac{1}{\tan \theta} = \frac{1}{\sqrt{29}} = \frac{\sqrt{29}}{29} \]

Final Answer

\[ \boxed{\sin \theta = \frac{\sqrt{870}}{30}} \]
