Suppose u and v are functions of x that are differentiable at x=0, and that u(0)=5,

u'(0)=-3,

v(0)=-1, and

v'(0)=2.

Find the values of the following derivatives at x=0.

a) (d/(dx))(uv)

My answer: 13 ok

b) (d/dx)(u/v)

My answer: -7 ok

c) (d/dx)(v/u)

d) (d/dx)(7v-2u)

For c and d, I do not know how to read this problem or approach it. I don't know what d stands for or what to do with the numbers surrounding it. Clueless. Clueless?, then how did you get the correct solutions for (a) and (b) ? d/dx just means take the derivative w/r to x.

#2y=(x^2+3)/x = x + (3/x) ... now take the derivative
