Question

if cos = 60 and
there is cos sin /3 what is the exact value in simplest form

Answer 1

I’m not quite sure what you mean — could you clarify? Common interpretations and their exact simplest forms:

- cos 60° = 1/2.
- sin 60° = √3/2.
- If you mean cos(π/3) and sin(π/3), those are the same as above: cos(π/3) = 1/2, sin(π/3) = √3/2.
- If you mean the product cos(π/3)·sin(π/3) = (1/2)(√3/2) = √3/4.
- If you mean (cos(π/3)·sin(π/3))/3 = (√3/4)/3 = √3/12.
- If you mean cos(sin(π/3)), that is cos(√3/2) (no simple exact algebraic value).

Which of these did you mean?
