Inverse Trigonometric Functions
Grade 12

Question:

<p>If we consider only the principal values of the inverse trigonometric functions, then the value of \(\tan^{-1}\left(\cos^{-1}\frac{1}{5} - \sin^{-1}\frac{4}{17}\right)\) is</p>
<p>(a) \(\frac{29}{3}\)</p>
<p>(b) \(\frac{29}{3}\)</p>
<p>(c) \(\frac{3}{29}\)</p>
<p>(d) \(\frac{3}{29}\)</p>

Step-by-Step Solution

Key Concept: Use principal value definitions and composition properties of inverse trigonometric functions
<p>This requires evaluation of inverse trigonometric compositions using principal values.</p>
