The value of sec 0 degrees is 1.
Understanding Secant
The secant (sec) function is a trigonometric function that is the reciprocal of the cosine (cos) function. Mathematically, this is represented as:
sec(θ) = 1 / cos(θ)
Calculating Sec 0 Degrees
To find sec 0°, we first need to know the value of cos 0°. The cosine of 0 degrees is 1. Therefore, we can calculate sec 0° as follows:
sec 0° = 1 / cos 0° = 1 / 1 = 1
Summary
| Function | Value at 0 degrees |
|---|---|
| cos 0° | 1 |
| sec 0° | 1 |
According to the reference from Cuemath, the value of sec 0° is indeed 1.
