Any value that is not zero.
A constant that’s not zero. A constant is a term with no variable part. So, a nonzero constant is a term with only has a coefficient that is not zero
a nonzero constant helps with “initial value problems”.. if you do not account for it, your answer will be wrong. think of physics:
x=x+xt+xt^2 where ‘x’ is the initial displacement. If you do not account for any initial conditions, your answer will be wrong.
A number that isn’t zero, like 2 or -2.
a coefficient that has either a positive or negative constant value, so any value that is not 0.
