    Differentials

    I need a little help with differentials.

    Determine the differentials d[uv], d[e^u], and d[cos u]. Then compute the differential of the function y=e^(-0.5)cos(4x).

    Where is your attempt at these.

    Also you need to provide more information, the first one for example:

    d(uv)

    What are we differentiating with respect to? What are constants and what are variables?

    Post back with the added information and you attempt and then we can go from there.
