csc pi/2

The exact value of csc(π2) csc ( π 2 ) is 1 .

Is csc pi 2 undefined?

The value of sin (pi) is 0, so the cosecant of pi must be undefined.

What is the value of csc P?

1 Answer. You cannot get an exact value; Considering that csc(x)=1sin(x) and that sin(π)=0 you get: csc(π)=1sin(π)=10 which cannot be calculated.

How do you find the value of csc 2?

The exact value of arccsc(2) is π6 . The cosecant function is positive in the first and second quadrants. To find the second solution, subtract the reference angle from π to find the solution in the second quadrant.

What is the value of SEC pi by 2?

The value of sec pi/2 is equal to the reciprocal of the x-coordinate(0). ∴ sec pi/2 = not defined.

What’s the derivative of csc?

The double derivative of csc x is csc x (cot2x + csc2x). The double derivative is nothing but the second derivative of a function which can be obtained by differentiating the first derivative of csc x.

How do you find the exact value of csc pi?

To find the value of csc π using the unit circle: Rotate ‘r’ anticlockwise to form pi angle with the positive x-axis. The cosec of pi equals the reciprocal of the y-coordinate(0) of the point of intersection (-1, 0) of unit circle and r.

What is cot 3pi2?

The value of cot 3pi/2 is 0. Cot 3pi/2 can also be expressed using the equivalent of the given angle (3pi/2) in degrees (270°). Since the cotangent function is a periodic function, we can represent cot 3pi/2 as, cot 3pi/2 = cot(3pi/2 + n × pi), n ∈ Z.

What is csc equal to?

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 csc of pi 1?

Trigonometry Examples

The exact value of csc-1(1) is π2 . The result can be shown in multiple forms.

What is Cotpi?

Cot pi is the value of cotangent trigonometric function for an angle equal to π radians. The value of cot pi is not defined.

What is the derivative of Cscx 2?

The derivative of csc(x) with respect to x is −csc(x)cot(x) – csc ( x ) cot ( x ) . Multiply −1 by 2 . Raise csc(x) to the power of 1 . Raise csc(x) to the power of 1 .

Is Secx differentiable at pi 2?

secx is undefined at −π2 and π2 , so it is not continuous on the closed interval, [−π2,π2] .
