## What is the exact value of sin 15 degrees?

Value of Sin 15 degree = (√3 – 1) / 2√2.

## What is the exact value of tan 105 degrees?

Complete step-by-step answer: By using specified tangent angle from the standard trigonometric ratios table i.e., tan60∘=√3, and tan450=1. Hence, the exact functional value of tan(105∘)=√3+11−√3.

## How do you solve sin 15 degrees?

Since, we know, Sin 15° = (√3–1)/2√2.

## How do you solve Sin degrees?

As an example, follow these steps to find the sine of 135 degrees:

1. Rewrite the angle, using the special angles from right triangles.
2. Choose the appropriate sum or difference formula.
3. Plug the information you know into the formula.
4. Use the unit circle to look up the sine and cosine values you need.

## How do you find the value of sin degrees?

= sin A cos B + cos A sin B, we can find the sine of (45° + 30°) to give sine of 75 degrees. We now find the sine of 36°, by first finding the cos of 36°. sin 18°: Now, the sine of 18 degrees comes from the sine of half of 36 degrees.

## How do you find the value of sin 50 degrees?

The sin of 50 degrees is 0.76604, the same as sin of 50 degrees in radians. To obtain 50 degrees in radian multiply 50° by / 180° = 5/18 . Sin 50degrees = sin (5/18 × .

## How do you find the sin of 30 degrees?

To find the value of sin 30 degree, we will use the following formula, Sinϴ = Perpendicular Hypotenuse. Thus, the value of Sin 30 degree is equal to 12(half) or 0.5. Just like the way we derived the value of sin 30 degrees, we can derive the value of sin degrees like 0°, 30°, 45°, 60°, 90°,180°, 270° and 360°.

## How do you convert sin to degrees without a calculator?

If sin(theta) = x, theta = arcsin(x) = approx x + (1/6) x^3+ (3/40) x^5 + (5/112) x^7 + (35/1152) x^9. Then you will have to change to degrees by multiplying by 180 / pi. Doing all that arithmetic by hand (which would be without a calculator) ?

## Can you do trigonometry without a calculator?

Until now, we have used the calculator to evaluate the sine, cosine, and tangent of an angle. However, it is possible to evaluate the trig functions for certain angles without using a calculator. This is because there are two special triangles whose side ratios we know!

## What are the 6 basic trigonometric functions?

There are six trigonometric ratios, sine, cosine, tangent, cosecant, secant and cotangent. These six trigonometric ratios are abbreviated as sin, cos, tan, csc, sec, cot.

## What is the exact value of tan 7Pi 4?

Tan 7Pi/4 Radians Tan 7pi/4 = tan 315 degrees. Our results of tan7pi/4 have been rounded to five decimal places.

## What is the exact value of tan 330 degrees?

Hence, the exact functional value of tan(330∘) is −1√3.

0.40402622532478

## How do you find the value of tan 22?

∴tan45∘=2tanθ1-tan2θ.

## What is the value of TAN 22 and half degree?

Answer. 22½° lies in the first quadrant. Therefore, tan 22½° is positive.

## Is Arctan the inverse of tan?

The arctan function is the inverse of the tangent function. It returns the angle whose tangent is a given number….arctan.

tan 30 = 0.577 Means: The tangent of 30 degrees is 0.577
arctan 0.577 = 30 Means: The angle whose tangent is 0.577 is 30 degrees.

## What is tangent equal to?

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

## What is tangent in math?

A tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency. The tangent to a circle is perpendicular to the radius at the point of tangency.

## What is the tangent of a function?

A tangent line to a function at a point is a line that is in contact with the graphical representation of the function only in that particular point. The tangent line is only touching the function (graph) in the specified point. In other words the tangent line is barely in contact with function (graph).

## What is CSC of an angle?

Definition. Cosecant. The cosecant of an angle in a right triangle is a relationship found by dividing the length of the hypotenuse by the length of the side opposite to the given angle. This is the reciprocal of the sine function.

## What does CSC stand for?
