1. Angle measure
Degrees are a unit of angle measure. A full circle is divided into 360 degrees. For example, a right angle is 90 degrees.
A degree has the symbol ° and so ninety degrees would written 90°. Another unit of angle measure is the
2. Degree of a term
The degree of a term is the exponent of the term. For example the term
has a degree of 2.
If the term has more than one variable multiplied together it is the sum of the exponents. For example
has a degree of 6 (4+2).
If there is no exponent, the degree is 1, since
If the term is just a constant its degree is zero. Recall that
and so any constant (say 9) could be re-written:
3. Degree of a polynomial
The degree of a polynomial is the highest degree of any term in the polynomial.
For example the polynomial
has a degree of 5 because the x5 term has the highest degree. See ("degree of a term" above).
This calculator is used to add and subtract angles in degrees, minutes and seconds. This angle form has each degree is divided into 60 minutes and each minute divided into 60 seconds. Used in astronomy and defining latitude and longitude.
