# Question: How Do You Find The Value Of Sin 15?

## What is value of sin30?

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..

## How do you find the exact value of sin 15?

Exact Value of sin 15°For all values of the angle A we know that, (sin A2 + cos A2)2 = sin2 A2 + cos2 A2 + 2 sin A2 cos A2 = 1 + sin A.Therefore, sin A2 + cos A2 = ± √(1 + sin A), [taking square root on both the sides]Now, let A = 30° then, A2 = 30°2 = 15° and from the above equation we get,More items…

## How do you find the value of sin 10?

For finding value of sin(10°), draw a line at 10° to the diameter from center.. Now, from the intersection of that line with the circle, draw a perpendicular line to the diameter line. “sin” is the vertical component. So measure the length of the perpendicular line drawn. Thats the sin value.

## How do you find the value of sin 75?

Answer. Sin(A+B) = Sin A Cos B + Cos A Sin B. Sin 75 = Sin ( 45 + 30) = Sin 45 Cos 30 + Cos 45 Sin 30. Sin 75 = (1 / √2) ( √3 / 2) + (1 / √2) ( 1 / 2) = [ √3 + 1] / 2√2.

## What is an exact value?

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 solve sin 45 degrees?

The hypothenuse AC can easily be calculated now: AC=√BC2+AB2=√12+12=√2 . The sine is defined as the ratio between the opposed side and the hypothenuse. Therefore, sin45o=1√2=√22 . In decimal form, it is roughly 0.7071067812 .

## What is sin180?

So, Sin 180 degree is +(sin 0) which is equal to +(0) Therefore, the value of sin 180 degrees = 0. The value of sin pi can be derived from some other trigonometric angles and functions like sine and cosine functions from the trigonometry table.

## What is the value of sin 15 in fraction?

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

## What is the value of sin 75 degree sin 15 degree?

Combine the numerators over the common denominator. The exact value of sin(15) sin ( 15 ) is √6−√24 6 – 2 4 .

## How do you solve for sin?

In any right angled triangle, for any angle:The sine of the angle = the length of the opposite side. the length of the hypotenuse.The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.The tangent of the angle = the length of the opposite side. the length of the adjacent side.

## What is sin60 value?

From the above equations, we get sin 60 degrees exact value as √3/2. In the same way, we can find the values for cos and tan ratios. The above values of trigonometry ratios are with respect to degrees.

## How do you find the value of sin 40?

Answer. If any angle x is in degree then it is equal to (x×π/180) unit in radian. (a+h)=(37×π/180+3π/180). h=3π/180.

## What is sin1 value?

0.8414709848The value of sin 1 is 0.8414709848, in radian. In trigonometry, the complete trigonometric functions and formulas are based on three primary ratios, i.e., sine, cosine, and tangent in trigonometry.

## Is sin 1 the same as CSC?

So far in this course, the only trigonometric functions which we have studied are sine and cosine. … The secant of x is 1 divided by the cosine of x: sec x = 1 cos x , and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x .
