## What is Secx

In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side.

In a formula, it is abbreviated to just ‘sec’.

sec.

## What are the six trigonometric ratios

There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant and cotangent. These six trigonometric ratios are abbreviated as sin, cos, tan, csc, sec, cot.

## What is the formula of trigonometry

Basic Trigonometric Function Formulas By using a right-angled triangle as a reference, the trigonometric functions and identities are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side.

## What is SOH CAH TOA

“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) (3) Other mnemonics include.

## Whats the opposite of Cos

The secant is the reciprocal of the cosine. It is the ratio of the hypotenuse to the side adjacent to a given angle in a right triangle.

## What is the formula of tan 3 Theta

What is the Formula of Tan 3x? Ans: Formula of tan3x = (3tanx – tan3x)/(1 – 3tan2x).

## What does cot mean in trigonometry

In a right angled triangle, the cotangent of an angle is: The length of the adjacent side divided by the length of the side opposite the angle. The abbreviation is cot.

## What is tan theta formula

⇒ tan x = sin x/cos x. or, tan theta = sin theta/cos theta (here, theta is an angle) The sine of an angle is equal to the length of the opposite side divided by the length of the hypotenuse side, while the cosine of an angle is the ratio of the adjacent side to the hypotenuse side.

## What is cot a Cosec a equal to

Complete step-by-step answer: We know that cotA=cosAsinA and cosecA=1sinA so, on putting these values in the above equation we get, ⇒cosAsinA+1sinA so, the new equation is cosA+1sinA. Now on using the above equation we will use the formulas sinθ=2sinθ2cosθ2 and cosθ=2cos2θ2−1. So, we got the value of cotA+cosecA=cotA2.

## What is cot Cosec and SEC

Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan. sec x = 1. cos x. cosec x = 1. sin x.

## How do you calculate tan

In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). In a formula, it is written simply as ‘tan’.

## What is sin cos and tan

Sin is equal to the side opposite the angle that you are conducting the functions on over the hypotenuse which is the longest side in the triangle. Cos is adjacent over hypotenuse. And tan is opposite over adjacent, which means tan is sin/cos. this can be proved with some basic algebra.

## What is trigonometry example

Trigonometric functions are used in obtaining unknown angles and distances from known or measured angles in geometric figures. … For example, csc A = 1/sin A, sec A = 1/cos A, cot A = 1/tan A, and tan A = sin A/cos A.

## How do you start trigonometry

Learn Trigonometry in 5 stepsStep 1: Review your all basics.Step 2: Start with the right angle triangles. … Example: A right angle have two sides 5 cm and 3 cm find the hypotenuse.Solution: Given opposite =5cm and adjacent=3 cm.Using Pythagoras theorem. … Step 4: Learn the other important function of trigonometry.More items…

## What is Theta equal to

Cosine theta equals x, sine theta equals y and tangent theta equals y over x, where x and y are the coordinates of the point on the terminal side of the angle. And the 3 new functions are secant theta, cosecant theta and cotangent theta. Secant theta is defined as 1 over x.
