# Quick Answer: What Is The Value Of Cot Inverse 1?

## Is SEC inverse of cos?

The secant is the reciprocal of the cosine.

The cotangent is the reciprocal of the tangent..

## What is the meaning of Tan 1?

The inverse tan of 1, ie tan-1 (1) is a very special value for the inverse tangent function. Remember that tan-1(x) will give you the angle whose tan is x . Therefore, tan-1 (1) = the angle whose tangent is 1. It’s also helpful to think of tangent.

## What angle is cos1?

The answer is 120°. With inverse cosine, we select the angle on the top half of the unit circle. Thus cos-1 (–½) = 120° or cos-1 (–½) = 2π/3. In other words, the range of cos-1 is restricted to [0, 180°] or [0, π].

## What is the value of cot 1?

Therefore, cot−1 x = nπ + α, where, (α ≠ 0, – π/2 ≤ α ≤ π/2) and ( – ∞ < x < ∞ ). Therefore, principal value of cot−1 √3 is π/6 and its general value = nπ + π/6.

## What is the value of cot inverse 0?

cot(0) = undefined.

## What is the value of SEC inverse 1?

01 Answer. sec−11=0 .

## What is the value of tan 1?

Using the unit circle we can see that tan(1)= pi/4. Since the “Odds and Evens Identity” states that tan(-x) = -tan(x). Tan(-1)= -pi/4. Knowing that tan is negative in quadrants 2 and 4.

## 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 the reciprocal of cot?

Secant is the reciprocal of cosine. … Cotangent is the reciprocal of tangent. Its abbreviation is cot.

## How do you find the value of cos 1?

If question is cos(1°), then Cos(1°) = 0.99984769515. If it was in radian, Cos(1 rad) = 0.54030230586. You can easily find the answer by googling it.

## What is the inverse of tan?

arctan functionThe arctan function is the inverse of the tangent function. It returns the angle whose tangent is a given number. Try this Drag any vertex of the triangle and see how the angle C is calculated using the arctan() function. Means: The angle whose tangent is 0.577 is 30 degrees.

## Can Cos equal 1?

Cos is also 1 when thet…” When theta is 0, cos is 1. Cos is also 1 when theta is 2 pi. Since 2 pi is the period of the unit circle, when you go around a distance equal to the circumference, you end up in the same spot.

## Is cot Tan 1?

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)
