Find the value of sec(θ) when θ = π/4 on the unit circle

Answer 1 To find the value of $ \sec(\theta) $ when $ \theta = \frac{\pi}{4} $ on the unit circle, we first recall that $ \sec(\theta) = \frac{1}{\cos(\theta)} $. At $ \theta = \frac{\pi}{4} $, the cosine of $ \theta $ is $ \cos(\frac{\pi}{4}) =...
