The grownth of the population in a particular country can be modeled by P(t)=P(Sub 0)e^.019t-220t where t represents time in years since 1998, and P(t) represents the population of the country. If after 8 years the population P(t) rose to 5,930,000. Find the initial population P(Sub 0)

when we integrate dx/x then we write "int dx/x = ln |x| + C".But why
we give "absolute value sign ( | x |)"?

I learned in Calculus that if y=f(x), then

d/dx g(y) = g'(f(x))f'(x)

but what if y is a vector? (x and g(x) are both scalars.) If g(y) is a function of an array y, and each element of y is a (possibly different) function of x, then how do I express the derivative of g(f(x)) with respect to x? Is there a generalized version of the chain rule for vectors?

I'm trying to understand neural nets and this keeps coming up.

i was thinking about using K=1/2*mv^2 but we don't know the mass here or we can use w=m*g*h..

Could someone explain, in as much detail as they are willing to give, How the contravariant tensors can be transformed into Covariant tensors? I understand that Contravariant tensors are like Tangents and Covariant are as normal vectors to the surface. Perhaps someone has a good reference for the relations because I am having a difficult time seeing it...
