## Trigonometry (11th Edition) Clone

$1.1054$
Step 1: We ensure that the calculator is in radian mode. Step 2: $\cot s=\frac{1}{\tan s}=0.5022$ Step 3: $\tan s=\frac{1}{0.5022}$ Step 4: $s=\tan^{-1} (\frac{1}{0.5022})$ Step 5: Using the inverse cosine function in the calculator, we type $\tan^{-1} (\frac{1}{0.5022})$ into the calculator and solve. Step 6: $s=\tan^{-1} (\frac{1}{0.5022})\approx1.1054$
