Secant is the reciprocal of cosine, so $sec(s) = \frac{1}{cos(s)}$. Given $sec(s) = 2.2426$, we find $cos(s) = \frac{1}{2.2426}$. Solving for $s$ in the interval [0, π/2], $s \approx 1.1086$.

Find the Value of S in the Interval [0, π/2] s=2.2426s = 2.2426s=2.2426

Find the Value of S in the Interval [0, π/2] $s = 2.2426$
