Solution
Solution Steps
Step 1: Understanding the Problem
We are given the composite function tan(tan^{-1}(x)), where x is a real number.
The goal is to find the exact value of this composite function.
Step 2: Applying the Solution Approach
For a trigonometric function followed by its inverse, such as tan(tan^{-1}(x)), the composite function simplifies to the argument of the inner function, which is x, provided x falls within the domain of the outer function.
In this case, since we are dealing with tan(tan^{-1}(x)), and given that x is within the domain of the outer function (all real numbers), the solution simplifies to x.
Final Answer:
The exact value of tan(tan^{-1}(x)) is -0.294, where x is -0.294 and falls within the domain all real numbers.
