## What is SEC equal to?

The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x ..

## Is SEC the opposite of Cos?

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

## 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 does cot mean in trigonometry?

In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just ‘cot’.

## 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 cos in terms of sin?

Sine and cosine are cofunctions. Therefore, the relationship sinx=cos(90−x) and cosx=sin(90−x) applies.

## What are the 6 basic trigonometric functions?

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

## What is the inverse of SEC?

The inverse secant function – arcsec For every trigonometry function such as sec, there is an inverse function that works in reverse. … So the inverse of sec is arcsec etc. When we see “arcsec A”, we interpret it as “the angle whose secant is A”.

## What are the formulas in trigonometry?

Basic Formulassin θ = Opposite Side/Hypotenuse.cos θ = Adjacent Side/Hypotenuse.tan θ = Opposite Side/Adjacent Side.sec θ = Hypotenuse/Adjacent Side.cosec θ = Hypotenuse/Opposite Side.cot θ = Adjacent Side/Opposite Side.

## What are the 3 basic trigonometric functions?

The three main functions in trigonometry are Sine, Cosine and Tangent.

## What are basic trig functions?

As functions sine, cosine, tangent, cotangent, secant, and cosecant are functions of a real argument x representing the radian measure of an angle. …

## How do you turn sin into cos?

The Basic Two: Sine and Cosine(1) Memorize: sine = (opposite side) / hypotenuse. … (2) sin A = cos(90° − A) or cos(π/2 − A) cos A = sin(90° − A) or sin(π/2 − A)(3) Memorize: … (4) tangent = (opposite side) / (adjacent side)(5) Memorize: … (6) tan A = cot(90° − A) or cot(π/2 − A) … (7) sec A = csc(90° − A) or csc(π/2 − A)

## What is cot on a calculator?

COT(x) returns the cotangent of x. The argument x must be expressed in radians. To convert degrees to radians you use the RADIANS function. The cotangent is the reciprocal of the tangent: ( x ) = 1 tan

## 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).

## Is sin 1 the same as CSC?

cosecant is the reciprical of the sin function or 1/sin(x) so that csc(x)*sin(x) = 1 when it is defined. The two can be confused since arcsin(x) is often denoted as sin^-1(x) and x^-1 is 1/x.

## Who is the SEC?

The SEC consists of 14 member institutions located in the U.S. states of Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, Missouri, South Carolina, Tennessee, and Texas.

## What does SOH CAH TOA mean?

Sine equals Opposite over Hypotenusewebsite feedback. SOHCAHTOA. A way of remembering how to compute the sine, cosine, and tangent of an angle. SOH stands for Sine equals Opposite over Hypotenuse. CAH stands for Cosine equals Adjacent over Hypotenuse.

## What is SEC and Cosec?

Secant (sec) is the reciprocal of cosine (cos) Cosecant (cosec) is the reciprocal of sin. Cotangent (cot) is the reciprocal of tan.

## Are cot and tan 1 the same?

tan x−1, sometimes interpreted as (tan(x))−1 = 1tan(x) = cot(x) or cotangent of x, the multiplicative inverse (or reciprocal) of the trigonometric function tangent (see above for ambiguity)

## What does cot mean?

small usually collapsible bed1 : a small usually collapsible bed often of fabric stretched on a frame. 2 British : crib sense 2b. cot. abbreviation. Definition of cot (Entry 3 of 3)

## 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 SEC (- theta?

sec(theta) = 1 / cos(theta) = c / b. tan(theta) = sin(theta) / cos(theta) = a / b. cot(theta) = 1/ tan(theta) = b / a. sin(-x) = -sin(x)
