Step 1.1.1

Evaluate $arccot (\frac{6}{5})$ .

$\arccos (x) - 1 \cdot 0.69473827 = 0$

Step 1.1.2

Multiply $- 1$ by $0.69473827$ .

$\arccos (x) - 0.69473827 = 0$

Step 2

Add $0.69473827$ to both sides of the equation.

$\arccos (x) = 0.69473827$

Step 3

Take the inverse arccosine of both sides of the equation to extract $x$ from inside the arccosine.

$x = \cos (0.69473827)$

Step 4

The result can be shown in multiple forms.

Exact Form:

$x = \cos (0.69473827)$

Decimal Form:

$x = 0.76822127 \dots$
