What is TOA CAH Soh?
“SOHCAHTOA” is a helpful mnemonic for remembering the definitions of the trigonometric functions sine, cosine, and tangent i.e., sine equals opposite over hypotenuse, cosine equals adjacent over hypotenuse, and tangent equals opposite over adjacent, (1) (2)
What is β in trigonometry?
The most commonly used letters for angle measures are α (alpha), β (beta), γ (gamma), and θ (theta). Also, many equations use the variable x to represent an angle measure. Algebra has conventional notation involving superscripts, such as the 2 in x2.
What is T stands for trigonometry ratio Toa?
TANGENT = Opposite ÷ Adjacent Given a right angle triangle and one of its interior angles a, the tangent of angle a, written tan(a), equals to: its opposite side length divided by its adjacent side length.
What is abbreviation in trigonometry?
trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
What does gamma mean in trig?
Angle-related Symbols
hSymbol Name | Explanation | Example |
---|---|---|
a , b , c , (alpha), (beta), (gamma), (theta), (phi) | Variables for angles | α + β < γ |
∘ | Degree symbol | α = 180 ∘ – β |
rad | Radian symbol | π rad = 180 ∘ |

What is Omega in trig?
ω is called “angular frequency” in physics and engineering, and has units of radians/second. Since radian is a “dimensionless unit” (because angle is defined as the ratio of arclength along a circle to the radius of said circle), the radian unit is often not written.
Is Sohcahtoa real?
SOHCAHTOA is a mnemonic device used to remember the ratios of sine, cosine, and tangent in trigonometry.
What does cosec stand for?

How do you write Cosecant?
Cosecant is one of the main six trigonometric functions and is abbreviated as csc x or cosec x, where x is the angle. In a right-angled triangle, cosecant is equal to the ratio of the hypotenuse and perpendicular. Since it is the reciprocal of sine, we write it as csc x = 1 / sin x.
What is trigonometry in math?
Written By: Trigonometry, the branch of mathematics concerned with specific functions of angles and their application to calculations. There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).
What are the 6 trigonometric functions in trigonometry?
Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc). These six trigonometric functions in relation to a right triangle are displayed in the figure.
What do the 9 letters mean in trigonometry?
These 9 letters are a memory aid to remember the ratios for the three primary functions – sin, cos and tan. Pronounced a bit like “soaka towa”. See Sohcahtoa. The ratios are constant Because the functions are a ratioof two side lengths, they always produce the same result for a given angle, regardless of the size of the triangle.
What does X mean in trigonometry?
“x” represents the measure of ther angle in either degrees or radians. Sine The three primary functions Cosine Tangent In the following table, note how each function is the reciprocal of one of the basic functions sin, cos, tan
