The cotangent function is defined as the length of the side adjacent over the length of the side opposite.
Step-by-step explanation:
The sine of an angle is defined as the length of the side opposite over the length of the hypotenuse.
The cosine of an angle is defined as the length of the side adjacent over the length of the hypotenuse.
The tangent of an angle is defined as the length of the side opposite over the length of the side adjacent.
The cotangent function is defined as the length of the side adjacent over the length of the side opposite.
The secant of an angle is defined as the length of the hypotenuse over the length of the side adjacent.
The cosecant of an angle is defined as the length of the hypotenuse over the length of the side opposite.

Answer:
-11
Step-by-step explanation:
To evaluate an expression with variables, replace the variables with what the question tells you to.
Replace "x" with 3. Replace "y" with -2.
-x + 4y
= -(3) + 4(-2) Multiply 4 and -2 first to get -8
= (-3) + (-8) Add normally. -3 + (-8) is the same as (-3) - 8.
= -11 Answer
Therefore the solution is -11.
To arrange the given polynomial in descending order of x, we only look at the exponent of x in each term and then write it in decreasing order of the value. We do as follows:
2xy^4 + 2x^2y − 3y^2 + 10x^3<span>
10x^3 + 2x^2 + 2xy^4 - 3y^2
The degree of the third term would be 5. The degree of a term is the sum of the exponents of the variables involved in the term.
