#1 Suppose u and v are functions of x that are differentiable at x=0, and that u(0)=5,
Find the values of the following derivatives at x=0.
My answer: 13
My answer: -7
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.
Find dy/dx by multiplying the factors first, then differentiating.
(I know how to do this be differentiating first, then multiplying the factors, but not the other way around...)
((x^2+3)(x) + (x^2+3)(x))/x^2
3x + 3/x
How do you do these...?
