Answer:

False

Step-by-step explanation:

The given equation is

[tex]\cos(t)=\frac{5}{3}[/tex]

The range of values of the cosine function lies between [tex]-1\leq \cos(t) \leq 1[/tex]

But the given value is [tex]\frac{5}{3}=1\frac{2}{3}[/tex]. This does not belong to the given range.

Therefore there is no value of [tex]t[/tex] so that [tex]\cos(t)=\frac{5}{3}[/tex]

holds.
