What is the value of Cosec 90 degree?

The exact value of cosec 90 degrees is 1.

What is the value of cos at 90 degree?

Cos 90° = 0

Also, it is easy to remember the special values like 0°, 30°, 45°, 60°, and 90° since all the values are present in the first quadrant. All the sine and cosine functions in the first quadrant take the form √(n/2) or √(n/4). Once we find the values of sine functions it is easy to find the cosine functions.

Is cosec 90 not defined?

Solution: From the trigonometric identities, we know, sec (90°) = undefined (∞) and cosec 90° = 1. Therefore, the value of 2 sec (90°) / 3 cosec (90°) = undefined.

What is the formula of cosec 90 Theta?

cosec(90+θ)=secθ

What is the value of 90 angle?

What is the exact value of sin 90 degrees? The exact value of sin 90 degrees is equal to 1.

Sec (90- Ө) = Cosec Ө and Cosec (90- Ө) = Sec Ө

What is cosec?

Cosecant Formula. Cosecant is one of the six trigonometric ratios which is also denoted as cosec or csc. The cosecant formula is given by the length of the hypotenuse divided by the length of the opposite side in a right triangle.

What is cosec 45?

Cosec 45 degrees is the value of cosecant trigonometric function for an angle equal to 45 degrees. The value of cosec 45° is √2 or 1.4142 (approx).

What is the value of cosec?

The value of cosec 0 degrees is undefined(∞). Cosec 0 degrees in radians is written as cosec (0° × π/180°), i.e., cosec (0π) or cosec (0).

What is the value of cosec 60 degree?

Cosec 60 degrees is the value of cosecant trigonometric function for an angle equal to 60 degrees. The value of cosec 60° is 2/√3 or 1.1547 (approx).

What is the value of cot 90 Theta?

cot (90° + θ) = - tan θ.

What is the value of cosec 30 degree?

The value of cosec 30° is equal to the reciprocal of the y-coordinate (0.5). ∴ cosec 30° = 2.

What is the value of cosec 270 degree?

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

How do you solve sin 90?

The value of sin 90 degrees can be calculated by constructing an angle of 90° with the x-axis, and then finding the coordinates of the corresponding point (0, 1) on the unit circle. The value of sin 90° is equal to the y-coordinate (1). ∴ sin 90° = 1.

What is the value of cosec 150?

The value of cosec 150° is equal to the reciprocal of the y-coordinate (0.5). ∴ cosec 150° = 2.
