$co t^{- 1} (- \sqrt{5})$

Short Answer

Expert verified

Value of the expression $co t^{- 1} (- \sqrt{5})$ islocalid="1646553713675" $\begin{array}{rcl} - 0.42 \end{array}$ .

Step by step solution

Step 1. Given information

An expression is $c o t^{- 1} (- \sqrt{5})$ .

Step 2. Value of the expression.

Consider the expression $c o t^{- 1} (- \sqrt{5})$ .

Use the formula: localid="1646553645353" $c o t^{- 1} (x) = \tan^{- 1} (\frac{1}{x})$ .

Put $x = - \sqrt{5}$ .

So,

localid="1646553702817" $\begin{array}{rcl} c o t^{- 1} (- \sqrt{5}) & = & \tan^{- 1} (\frac{1}{- \sqrt{5}}) \\ = & - 0.42 \end{array}$
