Question

There are values of t so that the equation cost=5/3 holds
true or false​

Answer 1

False

Explanation:

The given equation is

`\cos(t)=(5)/(3)`

The range of values of the cosine function lies between
`-1\leq \cos(t) \leq 1`

But the given value is
`(5)/(3)=1(2)/(3)`. This does not belong to the given range.

Therefore there is no value of
`t` so that
`\cos(t)=(5)/(3)`

holds.
