Answer
$0.716386406$
Work Step by Step
cot (arccos $0.58236841)=\cot (\cos^{-1} 0.58236841)$
To find $\cot (\cos^{-1} 0.58236841)$, we first need to find $\cos^{-1} 0.58236841$,
Ensuring that the calculator is in radians, we type $\cos^{-1} 0.58236841$ into the calculator and solve:
$\cos^{-1} 0.58236841\approx0.9491572238$
$\cot (\cos^{-1} 0.58236841)$ now becomes $\cot (0.9491572238)$. We know that $\cot (0.9491572238)=\frac{1}{\tan (0.9491572238)}$
Typing $\frac{1}{\tan (0.9491572238)}$ into the calculator and solving:
$\frac{1}{\tan (0.9491572238)}\approx0.716386406$
Therefore, $\cot (\cos^{-1} 0.58236841)\approx0.716386406$.
