cot(beta) does not exist
color(white)("XXX")because cos(beta)=5 is an invalid equation.

Explanation:

The cos function has a range of [-1,+1]

There is no value beta for which cos(beta)=5

Since AA beta in RR, cos beta in [-1,1], there can not be any beta such that cos beta=5. Hence, we can't find cot beta.
