Homework Statement
Solve for A:
dA/ds = -k s
Homework Equations
See problem statement
The Attempt at a Solution
I switched the equation around:
dA= -k s ds
Integrated:
A= -(k/2) (s^2+c)
Apparently, that is wrong and I see that the answer should be:
A= -(k/2) (s^2-b^2)
My question is: Why must the constant of integration subtract from s^2? Why couldn't it add to it?
