Question

find the smallest non negative value for x in degrees that makes the equation cot (x) = 0 true.

Answer 1

It is given that,

cot (x) = 0

To find the smallest non-negative value for x in degrees:

So that,

$\begin{gathered} \cot (x)=0 \\ \cot (x)=\cot (90^{\circ}) \\ x=90^{\circ} \end{gathered}$

Hence, the smallest value of x is 90 degrees.
