## What is sec csc and cot?

The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x . 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 .

How do you remember Sin Cos Tan csc sec cot?

Or, to remember all six functions, Sin, Cos, Tan, Cot, Sec, and Csc, memorize the syllables O/H, A/H, Oh/Ah, Ah/Oh, H/A, H/O (i.e. /oʊ ə ˈoʊ. ə əˈoʊ hə ˈhoʊ/). Longer mnemonics for these letters include “Oscar Has A Hold On Angie” and “Oscar Had A Heap of Apples.”

Are csc and sec complementary?

Cosecant is the complementary function of secant.

### What is sec the opposite of?

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.

Is cot sec a csc?

Math.com Trig Functions. The functions are usually abbreviated: sine (sin), cosine (cos), tangent (tan) cosecant (csc), secant (sec), and cotangent (cot).

Is SEC the opposite of Cos?

The secant ( sec ⁡ ) (\sec) (sec) 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.

#### Is CSC a sin?

We know that the cosecant is the reciprocal of the sine. Since sine is the ratio of the opposite to the hypotenuse, cosecant is the ratio of the hypotenuse to the opposite.

What is CSC math?

more In a right angled triangle, the cosecant of an angle is: The length of the hypotenuse divided by the length of the side opposite the angle. The abbreviation is csc. csc θ = hypotenuse / opposite.

What is the opposite of CSC?

Cosecant Function: csc(θ) = Hypotenuse / Opposite. Secant Function: sec(θ) = Hypotenuse / Adjacent.

## Is sec the inverse of cos?

How to find the values of CSC, SEC and cot?

In this section, you will learn how to find the values of the trigonometric ratios csc, sec and cot. The formulas given below can be used to find the trigonometric ratios csc, sec and cot. csc θ = Hypotenuse / Opposite side sec θ = Hypotenuse / Adjacent side

What is the difference between SEC, cosec and cot?

Sec, Cosec and Cot. 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 -1 x (sometimes written as arccos x).

### Is the formula for COT X the same as sec x?

cosec x = 1. sin x. cot x = 1 = cos x. tan x sin x. Note, sec x is not the same as cos -1 x (sometimes written as arccos x). Remember, you cannot divide by zero and so these definitions are only valid when the denominators are not zero. Example. If sec x = 2, cos x = ½, x = 60º. Graphs of sec x and cosec x.

Which is the opposite side of CSC C and cot C?

In the right triangle shown below, find the values of csc C, sec C and cot C. 90° is at ∠A. So the side which is opposite to 90° is known as hypotenuse. The side which is opposite to ∠C is known as opposite side. The remaining side is known as adjacent side.
