    Is something wrong with my calculator?

    i have to find the value of the function and use reference angles.
    sin 3.42 (radians) = -0.2748
    when i use reference angle, sin(3.42 - pi) = -sin .28.
    when i plug -sin .28 in the calculator, i get -0.2764. is the answer wrong?
    does it have to have exactly the same as the value of sin 3.42?? These problems are worth like 10 pts each
    Help!!

    Help!!
    You are using 3.14 instead of \pi

    the error comes from rounding see the immage below.

    I hope this helps
