I am not sure exactly what you're asking, but it seems they want you to differentiate the equation and then write it as a differential, meaning separate the dy/ds terms so would be dy = (the derivative of y) . ds
Does that help at all?
I'm trying to do a homework assignment, I've gotten all the problems right but the two remaining. They both involve differentials.
"Find the differential of the function"
I thought this would just mean to take the derivative of what remains, but in the area to enter the response it just says "Dy=" rather than "dy/dx=" leading me to believe there's something I'm missing here. Could somebody walk me through doing this problem?
