Solution
Solution Steps
To find the exact value of the remaining five trigonometric functions given \(\tan \theta = \sqrt{29}\), we can use the following steps:
Use the definition of \(\tan \theta\) to find \(\sin \theta\) and \(\cos \theta\).
Use the Pythagorean identity to find \(\sin \theta\) and \(\cos \theta\).
Calculate \(\csc \theta\), \(\sec \theta\), and \(\cot \theta\) using the reciprocal identities.
Solution Approach
Given \(\tan \theta = \sqrt{29}\), we know \(\tan \theta = \frac{\sin \theta}{\cos \theta}\).
Assume \(\sin \theta = \sqrt{29} \cos \theta\).
Use the Pythagorean identity: \(\sin^2 \theta + \cos^2 \theta = 1\).
Solve for \(\cos \theta\) and then find \(\sin \theta\).
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
