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.
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.
In geometry, angles are studied mostly in relation to each other. In Trigonometry, angles are studied in relation to side lengths and triangles.
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.
It depends. Between 9th to 12th.
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.
identity is a special information related to a particular person and equation is a way of writing a formula with the sign (=)
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
Trigonometry is specificly the study of a right triangle. For example, what is the cosine? Geometry is the study on shapes.
Expression has no answer. a equation has an answer
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.
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.
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.
In geometry, angles are studied mostly in relation to each other. In Trigonometry, angles are studied in relation to side lengths and triangles.
an equation has an equals sign.
An equation can lead to a solution.
The equation for calculating the phase difference between two waves is: Phase Difference (2 / ) (x) Where: Phase Difference is the difference in phase between the two waves is the wavelength of the waves x is the difference in position between corresponding points on the waves
Trigonometry is the study of plane and spherical triangles. Plane trigonometry deals with 2 Dimensional triangles like the ones you would draw on a piece of paper. But, spherical trigonometry deals with circles and 3 Dimensional triangles. Plane trigonometry uses different numbers and equations than spherical trigonometry. There's plane trigonometry, where you work with triangles on a flat surface, then there's spherical trigonometry, where you work with triangles on a sphere.
