Hello,
I have a problem with the cosine and sine on my Casio Graph 65 calculator, as it gives me incorrect results. Could someone help me? Thank you in advance.

    The results may depend on the configuration of your angles.
    If the angles are in degrees or radians, the results will definitely be different.

      So you need to go to [shift] [menu] (which is set up) and change your angle measurement unit.
