## What’s the exact value of cos 30?

The exact value of cos(30) is √32 .

## What is COS 1 in radians?

The Value of the Inverse Cos of 1

As you can see below, the inverse cos-1 (1) is 0° or, in radian measure, 0 . ‘1’ represents the maximum value of the cosine function. As you can see from the graph below, cosine has a value of -1 at 0 and again at 2Π and 4Π and every 2Π thereafter.

## How is sin calculated?

Sine (sin) function – Trigonometry. In a right triangle, the sine of an angle is the length of the opposite side divided by the length of the hypotenuse. In any right triangle, the sine of an angle x is the length of the opposite side (O) divided by the length of the hypotenuse (H).

## How do you find tangent?

In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). In a formula, it is written simply as ‘tan’. Often remembered as “SOH” – meaning Sine is Opposite over Hypotenuse.

## What is COS 60 as a fraction?

Cos(60°) = 1/2. Sin(60°) = 2/3. Tan(60°)= 3. Cos(30°) = 2/3.

## What is the exact value of tan − π?

## How do you find the inverse of sin 1?

The Value of the Inverse Sin of 1

As you can see below, the inverse sin-1 (1) is 90° or, in radian measure, Π/2 . ‘1’ represents the maximum value of the sine function . It happens at Π/2 and then again at 3Π/2 etc..

## What is the inverse of sin?

The inverse of the sin function is the arcsin function. But sine itself, would not be invertible because it’s not injective, so it’s not bijective (invertible). To obtain arcsine function we have to restrict the domain of sine to [−π2,π2] .

## What is the inverse of sin 1 2?

We know that sin(π6)=12 and so, sin(−π6)=−12 . Therefore, the (principal) inverse sine of −12 is −π6 .
