 # Question: What Is Tan15?

## Is Tan Sin Cos?

The tangent of x is defined to be its sine divided by its cosine: tan x = sin x cos x .

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

## What is tan 30 degrees in radians?

30 DegreesAngleTan=Sin/Cos30°1 √3 = √3 345°160°√3

## What is sin A B C?

sin (A – B + C) = sin [( A – B) + C] = sin (A – B) cos C + cos (A – B) sin C, [applying the formula of sin (α + β)]

## How do you calculate tan 50?

tan(a – b) = sin(a – b)/cos(a – b)Assuming you remember that sin(a + b) = sin a cos b + cos a sin b:And that cos(a + b) = cos a cos b – sin a sin b:Then I am going to work it out one more time here because I can’t seem to remember the formula for the tan(a + b) but if I write it out here:More items…

## What is the value of tan75?

tan(75°) = (√(3) + 1)/(√(3) – 1).

## What is the exact value of tan 3pi 4?

The exact value of tan(π4) tan ( π 4 ) is 1 .

## How do you find the degree of a tangent?

Find the angle of elevation of the plane from point A on the ground.Step 1 The two sides we know are Opposite (300) and Adjacent (400).Step 2 SOHCAHTOA tells us we must use Tangent.Step 3 Calculate Opposite/Adjacent = 300/400 = 0.75.Step 4 Find the angle from your calculator using tan-1

## What is tan value?

Tangent or Tan function is defined as a value (or the ratio) obtained by dividing the Opposite Side by Adjacent Side with reference to angle being measured in a Right Angled Triangle. … The value of Tangent function varies from a infinite negative value (e.g. 90.00001) to positive infinite value (e.g. 89.99999).

## Is the value of tan 30?

The value of tan 30 degrees is 1/√3. … In trigonometry, the tangent of an angle in a right-angled triangle is equal to the ratio of opposite side and the adjacent side of the angle. Tan 30 degrees is also represented by tan π/6 in terms of radians. The exact value of tan 30° is 0.57735.

## Why is tan 90 undefined?

At 90 degrees we must say that the tangent is undefined (und), because when you divide the leg opposite by the leg adjacent you cannot divide by zero. In the third quadrant the hypotenuse extended will now meet the tangent line above the x-axis and is now positive again.

## What is the sin of 30 in degrees?

The value of sin 30 degrees is 0.5. Sin 30 is also written as sin π/6, in radians. The trigonometric function also called as an angle function relates the angles of a triangle to the length of its sides.

## What is value of tan15?

So, the approximate value of tan15° is 0.269.

## Is tan 15 positive or negative?

tan 15= −2√3±√12+42 . Neglect negative value for x, as tan 15 would be positive in the 1st quadrant.
