How would you explain to someone who has not yet studied trigonometry the difference between an identity and an equation?

An identity is true for all values of the variable whereas an equation is true for only a finite number of values.
For example,
Identity: (x + 2)3 = x3 + 6x2 + 12x + 27 is true, whatever the value of x.
But
Equation: x3 - x = 0 is true only when x = -1, 0 or 1.

What is the difference between calculus and trigonometry?
Calculus is the study of instantaneous and cumulitive growths of functions with respect to two or more variables. Trigonometry is the study of angles, specifically in triangles.
What is the difference between angles of trigonometry and angles of geometry?
In geometry, angles are studied mostly in relation to each other. In Trigonometry, angles are studied in relation to side lengths and triangles.
How do you find amplitude in trigonometry?
The amplitude of a sine (or cosine) curve is the difference between the maximum and minimum values of the curve, measured over a whole cycle.
What grade do you learn trigonometry?
It depends. Between 9th to 12th.
How is trigonometry helpful in the field of construction?
In construction, Trigonometry is used to show how stress and force are directed along supports which are not vertical or horizontal. It is alos used to find the lengths of such components of a building, as well as the angles between parts.
What is the difference between identity and an equation?
identity is a special information related to a particular person and equation is a way of writing a formula with the sign (=)
What is the difference between identity and a conditional equation?
Identity: An equation satisfied by every number that is a meaningful replacement for the variable. Example: 3(X+1)=3X+3Conditional Equation: An equation that is satisfied by some number but not others, such as 2X=4
What is the difference between trigonometry and geometry?
Trigonometry is specificly the study of a right triangle. For example, what is the cosine? Geometry is the study on shapes.
What is the difference between equal two lines and identical three lines in maths?
Three lines between two equations means that there is an identity present. This means that whatever numbers you put into the equation it will always equal the equation on the other side.
What is the difference between an equation and an expression?
Expression has no answer. a equation has an answer
What is the difference between calculus and trigonometry?

What is the relationship between nature and your identity?
The difference between nature and your identity is that nature can represent where you came from and your common surroundings, and identity is shown by how you grew up by your nature.
What is the difference between college trigonometry and high school math?
The difference between college trigonometry and high school math is that college courses tend to be more focused in one subject. High school courses tend to provide the student with a broad understanding of math.
What is the difference between personality and identity?
Personality is the way they act and identity is looks…. Hope this helps!!
What is the difference between angles of trigonometry and angles of geometry?
In geometry, angles are studied mostly in relation to each other. In Trigonometry, angles are studied in relation to side lengths and triangles.
How would you determine the difference between a solution and an equation?
An equation can lead to a solution.
What is the difference between quadratic equation and quadratic expression?
an equation has an equals sign.
