In fact, the value returned by the cosecant function is the angle of zero or one hundred and eighty degrees is considered undefined because the equation csc (θ ) = 1/sin(θ) would involve division by zero. The same is true for an angle of three hundred sixty degrees (360°).

What is the angle for which the cosecant is undefined?

Trigonometric functions are undefined when representing fractions The denominator is zero. The cosecant is the inverse of the sine, so the cosecant of any angle x for which sin x = 0 must be undefined because its denominator is equal to 0. The value of sin(0) is 0, so the cosecant of 0 must be undefined.

Why is csc 180 undefined?

csc(180°)=1sin(180°)=10. Since we divide by 0 it is undefined…the « opposite side » of this triangle does not exist, so we call this cosecant undefined.

Which theta value is undefined by csc?

csc(θ) is not defined in θ=0θ=π and θ=2π , but we can use a calculator to get information about the behavior csc(θ) close to these values.

In which of the following angles is the secant function undefined?

In fact, the value returned by the secant function for any angle Ninety degrees or two hundred and seventy degrees is considered undefined because the equation sec (θ ) = 1/cos(θ) would involve division by zero.

Can the angle be uncertain?

we can use line undefined. That is, we can define an angle as an angle created where two are not parallel…

What is the value of CSC Theta?

However, as the value of sin (θ ) approaches zero, the value of csc (θ ) tends to to infinity. Therefore, the value of csc (θ ) when sin (θ ) equals 0 is said to be undefined.

What is the duration of the CSC?

Explanation: By definition, csc(x)=1sin(x) .Therefore, its period is the same as that of sin(x), i.e. 2π .

Why is sec270 undefined?

At zero degrees, this tangent length will be zero. Therefore, tan(0)=0. …in the third quadrant, the extended hypotenuse will now intersect the tangent above the x-axis, which is now positive again.At 270 degrees we again get undefined (und) results because we can’t divide by zero..

What is the value of csc 270?

Since the cosecant function is the inverse of the sine function, 1 / sin 270° = csc270°.

What is the value of Cosec 180 degrees?

Therefore, the value of cos 180° is -1.

What degree of tan is undefined?

What is a cotangent?

The cotangent (Figure 8) is Draw a tangent to the unit circle through point B of the perpendicular diameter. The tangent is the tangent segment between the tangent A and the intersection of the tangent and the radius line (D, E, etc., Figure 7).

cos (- 60?

because 60 = 0.5.

What is the reference angle for the 240 angle?

A 240 degree angle is between 180 and 270 degrees, so its terminal side is in QIII. Perform the action indicated by that quadrant. Subtract 180 from 240.You will find that 240 – 180 = 60, so the reference angle is 60 degrees.
