The **secant is the reciprocal of the cosine**. The cotangent is the reciprocal of the tangent.

## Is sec just cos flipped?

**Secant is the reciprocal of cosine**. Its abbreviation is sec. To determine sec, just flip cos over. Cotangent is the reciprocal of tangent.

## What is the inverse of sec?

So the inverse of sec is **arcsec** etc. When we see “arcsec A”, we interpret it as “the angle whose secant is A”. Means: The angle whose secant is 2.0 is 60 degrees.

### What is the derivative of SEC?

The derivative of sec x with respect to x is **sec x · tan x. i.e.**, it is the product of sec x and tan x. We denote the derivative of sec x with respect to x with d/dx(sec x) (or) (sec x)’.

### Is CSC just sin flipped?

Cosecant is **the reciprocal of sine**. Its abbreviation is csc. To determine csc, just flip sin over. Secant is the reciprocal of cosine.

### What is a sin in math?

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).

### Is YX a tan?

The unit circle definition is **tan**(theta)=y/x or tan(theta)=sin(theta)/cos(theta). The tangent function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. Tangent is also equal to the slope of the terminal side. … Like we have for the sine and cosine.

### What is secant formula?

The secant formula helps in finding out the hypotenuse, the length, and the adjacent side of a right-angled triangle. The formula is **sec θ = H/B**.

### What is the difference between cosine and secant?

As nouns the difference between secant and cosine

is that secant is (geometry) a **straight line that intersects a curve at two or more points** while cosine is (trigonometry) in a right triangle, the ratio of the length of the side adjacent to an acute angle to the length of the hypotenuse symbol: cos.

### How do you find the inverse of secant?

The inverse function of secant. Basic idea: To find sec^{–}^{1} 2, we ask “what angle has secant equal to 2?” The answer is 60°. As a result we say that sec^{–}^{1} 2 = 60°. In radians this is **sec ^{–}^{1} 2 = π/3**.

### What does CSC mean in 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 cosine maths?

The cosine (often abbreviated “cos”) is **the ratio of the length of the side adjacent to the angle to the length of the hypotenuse**. And the tangent (often abbreviated “tan”) is the ratio of the length of the side opposite the angle to the length of the side adjacent.

### 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.

### How was sine discovered?

Sine was **introduced by Abu’l Wafa in 8th century**, as a more convenient function, and gradually spread first in the Muslim world, and then to the West. (But apparently it was used in India centuries before him), as a more convenient function. However this new notation was adopted very slowly, it took centuries.

### Is Sine a Scrabble word?

**Yes**, sine is in the scrabble dictionary.

### How do you write cosecant?

Cosecant (**csc**) – Trigonometry function

In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just ‘csc’.

### How do you do Arcsin?

arcsin**(x) = π/2 – arccos(x)**

### What is the inverse of cosine?

**The arccos function** is the inverse of the cosine function. It returns the angle whose cosine is a given number. … Means: The angle whose cosine is 0.866 is 30 degrees. Use arccos when you know the cosine of an angle and want to know the actual angle.

### What is csc?

A CSC is essentially **a kiosk with a personal computer**, a wireless connection and other equipment. … Other services available are expected to include computer training, telemedicine delivery, office applications, CD burning, scanning, printing and digital imaging. The CSC project was begun in 2006.

### Is Cosecant the same as sin 1?

It is important to note that there is a big difference between the reciprocal value csc θ and sin^{–}^{1}x. The cosecant function means **1/sin θ**, while the second involves finding an angle whose sine is x.

### What’s the derivative of csc?

cscx=**1sinx**. From Derivative of Sine Function: ddx(sinx)=cosx.
