# What Is SEC Equal To?

## How do you find the SEC?

The secant of an angle in a right triangle is the value found by dividing length of the hypotenuse by the length of the side adjacent the given angle.

The secant ratio is the reciprocal of the cosine ratio..

## What is the reciprocal of SEC?

The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).

## What does SOH CAH TOA mean?

sine equals opposite over hypotenuse”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 SEC (- theta?

The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta). … Secant theta is defined as 1 over x.

## Is cot the inverse of tan?

cot(x) = 1/tan(x) , so cotangent is basically the reciprocal of a tangent, or, in other words, the multiplicative inverse. arctan(x) is the angle whose tangent is x.

## What is a reciprocal identity?

In mathematics, a reciprocal of a number is the number that, when multiplied by the original number, produces 1. … In this example, 1/x is the reciprocal identity of x, and vice versa. In trigonometry, either of the non-90-degree angles in a right triangle can be defined by ratios called the sine, cosine and tangent.

## Is SEC a sin or cos?

Secant, cosecant and cotangent, almost always written as sec, cosec and cot are trigonometric functions like sin, cos and tan. Note, sec x is not the same as cos-1x (sometimes written as arccos x).

## What are the six trigonometric functions?

There are six main trigonometric functions:Sine (sin)Cosine (cos)Tangent (tan)Secant (sec)Cosecant (csc)Cotangent (cot)

## Is SEC the opposite of Cos?

The cosecant is the reciprocal of the sine. The secant is the reciprocal of the cosine.

## What is SEC trig function?

Secant (sec) – Trigonometry function In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. … Of the six possible trigonometric functions, secant, cotangent, and cosecant, are rarely used.

## What does R mean in trigonometry?

When you work with angles in all four quadrants, the trig ratios for those angles are computed in terms of the values of x, y, and r, where r is the radius of the circle that corresponds to the hypotenuse of the right triangle for your angle.

## What are the basics of 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 Sine mean?

In mathematics, the sine is a trigonometric function of an angle. The sine of an acute angle is defined in the context of a right triangle: for the specified angle, it is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse).
