What is the exact value of sec 30?

The value of sec 30 degrees is 2√3. The value of sec 30 in radians is π/180°.

How do you find the exact value of sec 30 degrees?

For sec 30 degrees, the angle 30° lies between 0° and 90° (First Quadrant). Since secant function is positive in the first quadrant, thus sec 30° value = 2/√3 or 1.1547005. . . Since the secant function is a periodic function, we can represent sec 30° as, sec 30 degrees = sec(30° + n × 360°), n ∈ Z.

What is the value of SEC (- 30?

The exact value of sec(30) is 2√3 .

How do you find Sec value?

The sec of an angle in a right triangle is the ratio of the length of the hypotenuse to the length of the adjacent side. Secant can be easily replaced by cos x using the formula, sec x = 1 / cos x.

What is the value of cos 30 degrees?

Cos 30° = √3/2

Therefore, the exact value of cos 30 degrees is written as 0.8660 approx. √3/2 is the value of Cos 30° which is a trigonometric ratio or trigonometric function of a particular angle.

What does exact value mean?

Definition. Exact value is where you cannot estimate the value you must be precise, eg; you can't estimate something as being around about 5 centimetres; no you need an exact value such as 5.62. Exact value. Return to Mathematics Home.

How do you find the value of cos 47?

The value of cos 47 degrees can be calculated by constructing an angle of 47° with the x-axis, and then finding the coordinates of the corresponding point (0.682, 0.7314) on the unit circle. The value of cos 47° is equal to the x-coordinate (0.682). ∴ cos 47° = 0.682.

What is the cot of 30 degrees?

Cot 30 degrees is the value of cotangent trigonometric function for an angle equal to 30 degrees. The value of cot 30° is √3 or 1.7321 (approx).

What is the exact value of sec 90?

The value of sec 90 degrees is undefined.

What is a SEC math?

In a right angled triangle, the secant of an angle is: The length of the hypotenuse divided by the length of the adjacent side. The abbreviation is sec. sec(θ) = hypotenuse / adjacent.

How do you find the exact value of sec 105?

What is an exact answer?

As used in physics, the term "exact" generally refers to a solution that captures the entire physics and mathematics of a problem as opposed to one that is approximate, perturbative, etc. Exact solutions therefore need not be closed-form.

What is the exact value of cos 30 degree Brainly?

Cos 30 degrees is written as cos 30° and has a value in fraction form as √3/2. Cos 30° = √3/2 is an irrational number and equals to 0.8660254037 (decimal form). Therefore, the exact value of cos 30 degrees is written as 0.8660 approx.
