A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What is trigonometric identities?

Just as with any other identity, a trigonometric identity is a trigonometric statement (other than a definition), which is true for all values of the variable or variables.


What is the term trigonometry identity?

Trigonometric identities are trigonometric equations that are always true.


What is the Contribution of Pythagoras to trigonometry?

Pythagoras discovered many of the properties of what would become trigonometric functions. The Pythagorean Theorum, a2 + b2 = c2 is a representation of the fundemental trigonometric identity sin2(x) + cos2(x) = 1. 1 is the hypotenuse of any right triangle, and has legs length sin(x) and cos(x) with x being one of the two non-right angles. With this in mind, the identity upon which trigonometry is based turs out to be the Pythagorean Theorum.


What is sin squared x equals cos squared minus 2 sin x?

Since the word 'equals' appears in your questions it might be what is called a trigonometric identity, in other words a statement about a relationship between various trigonometric values.


Are trigonometric equations and trigonometric identities are the same thing?

In a trigonometric equation, you can work to find a solution set which satisfy the given equation, so that you can move terms from one side to another in order to achieve it (or as we say we operate the same things to both sides). But in a trigonometric identity, you only can manipulate separately each side, until you can get or not the same thing to both sides, that is to conclude if the given identity is true or false.


Why can't you square each side of the equation when verifying a trigonometric identity?

When we work to verify an identity, we work separately to both sides, and to see in the end if we have an equality. If we square both sides, that means that we assume that the equality exist, so we do not need to verify it. It looks for a solution, which will tell us if the statement is sometimes, always (identity), or never true.

How do you inverse one side of a trigonometric identity problem?

You must take the inverse of both sides, which is the equivalent of taking 1 divided by your terms.
