Find the Exact Value tan(43)

Problem

tan(43^∘)

Solution

1. Identify the task as finding the exact trigonometric value of tan(43^∘)

2. Determine if 43^∘ is a standard angle or can be expressed as a sum or difference of standard angles (such as 30^∘ 45^∘ or 60^∘.

3. Observe that 43^∘ is not a standard angle and cannot be simplified into a basic radical form using standard trigonometric identities or the unit circle.

4. Conclude that without a specific identity or approximation method, the exact value is simply the expression itself.

Final Answer

tan(43^∘)=tan(43^∘)
