How do you get CSC 270?

270° does not lies in 1st and 2nd Quadrant. Therefore, the exact value of cosec (270°) is – 1 .

How is csc calculated?

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 .

What is the value of 270 degree of Secant?

Sec 270 degrees is the value of secant trigonometric function for an angle equal to 270 degrees. The value of sec 270° is undefined.

How do you solve sin 270 degrees?

The value of sin 270 degrees can be calculated by constructing an angle of 270° with the x-axis, and then finding the coordinates of the corresponding point (0, -1) on the unit circle. The value of sin 270° is equal to the y-coordinate (-1). ∴ sin 270° = -1.

What is cos 270 equal to?

The value of cos 270 degrees can be calculated by constructing an angle of 270° with the x-axis, and then finding the coordinates of the corresponding point (0, -1) on the unit circle. The value of cos 270° is equal to the x-coordinate (0). ∴ cos 270° = 0.

Why is csc 180 undefined?

csc(180°)=1sin(180°)=10 . Because we're dividing by 0, it is undefined.

What is the exact value of csc 90 degrees?

Trigonometry Examples

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

What is the csc in math?

In a right angled triangle, the cosecant of an angle is: The length of the hypotenuse divided by the length of the side opposite the angle. The abbreviation is csc.

What is sec330?

Sec 330 degrees is the value of secant trigonometric function for an angle equal to 330 degrees. The value of sec 330° is 2/√3 or 1.1547 (approx).

Why is tan 270 undefined?

Explanation: For tan 270 degrees, the angle 270° lies on the negative y-axis. Thus tan 270° value is not defined.

What is the cot of 270 degrees?

What is the Value of Cot 270 Degrees? The value of cot 270 degrees is 0. Cot 270 degrees can also be expressed using the equivalent of the given angle (270 degrees) in radians (4.71238 . . .) ⇒ 270 degrees = 270° × (π/180°) rad = 3π/2 or 4.7123 . . .

Is Cos 270 undefined?

sin(270o)=−1,cos(2700)=0,tan(2700)= undefined.

Where is 270 on a circle?

It is equal to one-half a rotation around a circle. The larger angle at the intersection of a vertical and a horizontal line creates a 270 degree angle. It is equal to three-quarters of a rotation around a circle. A full circle creates a 360 degree angle.
