I am so confused with this question, someone please lead me to an understanding "There are values of t so that cos t= 5/3"

    Huh? There are values of t, so that cos(t) = 5/3 I think what it's saying is, cos(t) [Some number] is equal to 5/3 In other words, what number of cos will be 5/3, or 1.6666....

    since cosine cannot be larger than 1

    \[\cos(t) = 1.67 \space \space \space or \space \space \space \frac{ 5 }{ 3 }\] I guess you could plug in terms, like cos(1), cos(2), and if you can't find the value, then it's false.

    Not possible. There is no value greater than 1 on the unit circle

    the largest cosine can be is 1, the smallest is -1

    let her learn by plugging in infinite values until she reaches the conclusion?

    By definition, cos(x), sin(x) live between -1 and 1

    okay so no because cos cannot be bigger than 1
