Thread: 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:



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.
