To evaluate cot 30°, we first need to understand what cotangent means. Cotangent is the reciprocal of the tangent function. Therefore, cot 30° can be expressed as:
Understanding Cotangent
Mathematically, cotangent is defined as:
- cot θ = 1/tan θ
Finding tan 30°
Next, we need to find the value of tan 30°. The tangent of 30° is:
- tan 30° = 1/√3
Calculating cot 30°
Now, we can substitute this value into the cotangent formula:
- cot 30° = 1/tan 30° = 1/(1/√3) = √3
Final Result
Thus, the value of cot 30° is:
- cot 30° = √3
