Evaluate sec(0 degrees )

Problem

sec(0)

Solution

1. Identify the definition of the secant function in terms of the cosine function.

sec(θ)=1/cos(θ)

2. Substitute the given angle 0 into the expression.

sec(0)=1/cos(0)

3. Evaluate the cosine of 0 using the unit circle or trigonometric values.

cos(0)=1

4. Simplify the fraction to find the final value.

sec(0)=1/1

sec(0)=1

Final Answer

sec(0)=1
