## cutiecomittee123 one year ago 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"

1. Compassionate

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....

2. cutiecomittee123

well the choices given are true or false so it is a true or false question

3. anonymous

4. anonymous

since cosine cannot be larger than 1

5. Compassionate

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

6. cutiecomittee123

okay cool that makes sense then

7. anonymous

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

8. anonymous

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

@satellite73 , let her learn, my child. Let her learn.

10. zzr0ck3r

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

11. zzr0ck3r

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

12. cutiecomittee123

okay so no because cos cannot be bigger than 1

13. zzr0ck3r

correct
