 # Question: How Do You Find The Value Of Sin 60?

## What is sin equal to?

Always, always, the sine of an angle is equal to the opposite side divided by the hypotenuse (opp/hyp in the diagram).

The cosine is equal to the adjacent side divided by the hypotenuse (adj/hyp).

(1) Memorize: sine = (opposite side) / hypotenuse.

cosine = (adjacent side) / hypotenuse..

## How do you find tan 60 degrees?

To find the value of tan 60 degrees geometrically, consider an equilateral triangle ABC since each of an angle in an equilateral triangle is 600. Draw a perpendicular line AD from A to BC. In the same way, we can derive other values of tan degrees like 0°, 30°, 45°, 90°, 180°, 270° and 360°.

## 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 exact value of sin 45 degrees?

The exact value of sin(45°) sin ( 45 ° ) is √22 .

## 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 the exact value of CSC 90?

Trigonometry Examples The exact value of csc(90°) csc ( 90 ° ) is 1 .

## How do you find the value of sin 90?

Derivation to Find the Value of Sin 90 Degrees\sin x=\frac{1}{\csc x}\sin^{2}x+\cos ^{2}x=1.\sin (-x)=-\sin x.Sin 2x = 2 sin x cos x.

## Is the value of sin 60?

The exact value of sin(60°) sin ( 60 ° ) is √32 .

## What is the sign of 60 degrees?

Important Angles: 30°, 45° and 60°AngleTan=Sin/Cos30°1 √3 = √3 345°160°√3

## What is the value of sin 60 in trigonometry?

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. We can also mention the values with respect to radians.

## What is the exact value of CSC 60?

The exact value of csc(60°) csc ( 60 ° ) is 2√3 .

## What is the value of cot 60?

Trigonometry Examples The exact value of cot(60) is 1√3 .

## What is value of cos 90 degree?

Therefore, the value of cos 90 degrees is: Cos 90° = 0.

## What is the sin of 60 in radians?

Sines and cosines for special common anglesDegreesRadianssine90°π/2160°π/3√3 / 245°π/4√2 / 230°π/61/21 more row

## What fraction is cos 60?

You might know that cos(60°)=1/2 and sin(60°)=√3/2 as well as tan(45°)=1, but are 30, 45 and 60 the only angles up to 90° with a formula for their trig values?

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

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 the value of cot30?

Here , you are required to find the value of cot30 . By definition that means you are required to find the value of tan(90–30),which is also equal tan(60). Therefore, cot(30)=tan(90–60)=3^1/2.

## How do you find the value of sin?

sin(A + B) = 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°.

## Is sin 1 the same as CSC?

Sine of an angle is the side of the triangle that does not touch the angle divided by the hypotenuse. … cosecant is the reciprical of the sin function or 1/sin(x) so that csc(x)*sin(x) = 1 when it is defined. The two can be confused since arcsin(x) is often denoted as sin^-1(x) and x^-1 is 1/x.

## How do you find CSC 60 degrees?

1 Answercsc60=1sin60.Trig conversion table gives-> sin60=√32.csc60=2√3=2√33.
