## What is sin 30 degrees in fraction?

Therefore, Sin 30 degree equals to the fractional value of 1/ 2.

## How do you find sin 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°.

## What is 30 degrees as a fraction?

In trigonometry, the cosine function is defined as the ratio of the adjacent side to the hypotenuse. If the angle of a right triangle is equal to 30 degrees, and then the value of cosine at this angle i.e., the value of Cos 30 degree is in a fraction form as √3/2.

## Is Sin 30 negative?

Trigonometry Examples

Make the expression negative because sine is negative in the fourth quadrant. The exact value of sin(30) is 12 .

## Why TAN 90 is infinity?

we can say that The left limit of tan 90 is positive infinity, and the right limit tan 90 is negative infinity. … In this definition the tan of the angle is the opposite side to the angle divided by the adjacent side to the angle. You can’t have a triangle with a second 90° angle so tan (90°) is undefined.

## What is the value of sin 45 degrees?

The value of Sin 45 degree in decimal form is 0.7071067812. Sine is considered as one of the most important functions in trigonometry as it is used to find out the unknown values of the angles and length of the sides of a right-angle triangle.

## What’s the value of tan 30?

What is the exact value of tan 30 degrees? Tan 30 degree is equal to 1/√3 and its exact value is 0.57735.

## Is the value of sin 60?

From the above equations, we get sin 60 degrees exact value as √3/2.
