Multiple Choice

Write the trigonometric expression as an algebraic expression containing u and v.
- $\cos \left( \tan ^ { - 1 } \mathrm { u } + \tan ^ { - 1 } \mathrm { v } \right)$

• A) \(\frac { 1 + u v } { \sqrt { u ^ { 2 } + 1 } \cdot \sqrt { v ^ { 2 } + 1 } }\)
• B) \(\frac { 1 - u v } { \sqrt { u ^ { 2 } + 1 } \cdot \sqrt { v ^ { 2 } + 1 } }\)
• C) \(\frac { \mathrm { u } + \mathrm { v } } { \sqrt { \mathrm { u } ^ { 2 } + 1 } \cdot \sqrt { \mathrm { v } ^ { 2 } + 1 } }\)
• D) \(\frac { \sqrt { u ^ { 2 } + 1 } \cdot \sqrt { v ^ { 2 } + 1 } } { 1 - u v }\)
