Step-by-step explanation:
Your procedure is perfect, you're fine, however, bear in mind that, in a calculator when plugging in values for some functions, specially trigonometric ones, if you tell it cos(40), and the calculator is in Radian mode, it thinks you meant cosine of 40 radian units, if you give it cos(40) and it's in Degree mode, it thinks you meant 40°, and 40 radians is hugely different than 40°.
so, make sure your calculator is in Degree mode, as you'd have guessed, it isn't.
Given:
The polynomial is:

To find:
The degrees and determine whether it is a monomial, binomial, or trinomial.
Solution:
We have,

The highest power of the variable <em>x</em> in the given polynomial is 4. So, the degree of the polynomial is 4.
Monomial: Polynomial with one term.
Binomial: Polynomial with two terms.
Trinomial: Polynomial with three terms.
In the given polynomial, we have three terms
. So, the given polynomial is trinomial.
Therefore, the degree of the polynomial is 4 and it is a trinomial.
Approximately there are some of these on the we
