Answer:
u fine as hell
Step-by-step explanation:
Answer:
-3 - 2i
Step-by-step explanation:
conjugate of a+bi is a-bi, so conjugate of -3 + 2i = -3 - 2i
Answer:
Whats the problem?
Step-by-step explanation:
Answer:
The value of f(4) is 5. We can write f(4) = 5.
Step-by-step explanation:
Since it is given that
This is only possible if both the functions f(x) and g(x) are continuous at x = 4.
Now since the functions are continuous at x = 4 they need to be defined at the said value in accordance with the definition of continuous function.
Thus to obtain the limit we just put x = 4 in left hand side of the given relation thus getting
Now applying the given value of g(4) in equation 'i' we get
Answer:
Yes. It is a vector space over the field of rational numbers
Step-by-step explanation:
An element of the set has the form
where are rational coefficients.
The operations of addition and scalar multiplication are defined as follows:
The properties that , together the operations of vector addition and scalar multiplication, must satisfy are:
- Conmutativity
- Associativity of addition and scalar multiplication
- Additive Identity
- Additive inverse
- Multiplicative Identity
- Distributive properties.
This is not difficult with the definitions given. The most important part is to show that has a additive identity, which is the zero polynomial, that is closed under vector addition and scalar multiplication. This last properties comes from the fact that is a field, then it is closed under sum and multiplication.
