What is the reference number for pi 6?

What is the reference number for pi 6?

The reference number equals pi – the terminal point. For example, if your terminal point = 5 pi / 6, your reference number = pi / 6. Pi would equal 6 pi / 6, and 6 – 5 = 1 or 1 pi / 6.

What is the reference angle of 510 degrees?

Trigonometry Examples Find an angle that is positive, less than 360° , and coterminal with 510° . Subtract 360° 360 ° from 510° 510 ° . The resulting angle of 150° 150 ° is positive, less than 360° 360 ° , and coterminal with 510° 510 ° .

What is the reference angle of 210?

30°
Reference angle for 210°: 30° (π / 6)

What is the reference angle of PI 4?

Since π4 is in the first quadrant, the reference angle is π4 .

What is reference no?

A reference number is a unique identifier assigned to any financial transaction including those made using a credit or debit card. Reference numbers from each transaction on a customer’s account are usually included in a cardholder’s monthly statement.

What is the reference number for 7 pi?

7pi/6 is 6pi/6 +pi/6. This is 180° +30° = 210°. The reference angle is simply the acute angle in reference to the x axis.

How do you find the exact value of cos 510?

∴ cos 510° = cos(8.9011) = −√3/2 or -0.8660254. . . Explanation: For cos 510°, the angle 510° > 360°. Given the periodic property of the cosine function, we can represent it as cos(510° mod 360°) = cos(150°).

What is the exact value of sec 510?

-2/√3
Sec 510 degrees is the value of secant trigonometric function for an angle equal to 510 degrees. The value of sec 510° is -2/√3 or -1.1547 (approx).

How do you find the reference angle of 470?

Subtract 360° 360 ° from 470° 470 ° . The resulting angle of 110° 110 ° is positive, less than 360° 360 ° , and coterminal with 470° 470 ° .

What is the value of pi (π)?

The value of Pi (π) is the ratio of the circumference of a circle to its diameter and is approximately equal to 3.14159. In a circle, if you divide the circumference (is the total distance around the circle) by the diameter, you will get exactly the same number. Whether the circle is big or small, the value of pi remains the same.

How do you find the reference angle of 10pi/9?

3π/2 to 2π – fourth quadrant, so reference angle = 2π – angle. 10π/9 is a bit more than π, so it lies in the third quadrant. In this example, the reference angle is reference angle = angle – π = π/9. It couldn’t be easier! Simply: Type the angle into the box.

Why is Pi 22/7 an irrational number?

It is known that pi is an irrational number which means that the digits after decimal point never end being a non-terminating value. Therefore, 22/7 is used for everyday calculations. π is not equal to the ratio of any two number which makes it an irrational number.

Who is the first person to calculate pi?

The pi value was first calculated by Archimedes of Syracuse. The symbol π was first popularized by Leonhard Euler in 1737. What is the formula for calculating pi?
