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 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 the term trigonometry identity?

Trigonometric identities are trigonometric equations that are always true.

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.

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.

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.

What is 1 minus cos squared tetha?

According to the Pythagorean identity, it is equivalent to sin2theta.

What is the product of a trigonometric function and its reciprocal?

The product of any object and its reciprocal is always the identity. In the case of numbers, 1 (one).

What statement is an example of the Identity Property of Multiplication?

1 is the identity element of multiplication.

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.

What is a statement that is true for any number?

What is the word for a statement that is true for any number or variable?

An identity.
