What is the value of Cos 3pi by 4?

-0.7071067
The value of cos 3pi/4 is -0.7071067. . .. Cos 3pi/4 radians in degrees is written as cos ((3π/4) × 180°/π), i.e., cos (135°).

What is value of cos2π?

1
So, the value of cos 2pi is equal to the value of cos 0 which is 1. So, cos 2pi is equal to 1.

What degree is 3pi 4?

135 degrees
Hayden L. Therefore by substitution 3×π4 is equal to 3×1804 which equals 135 degrees.

How do you find Cos 3pi?

The value of cos 3pi can be calculated by constructing an angle of 3π radians with the x-axis, and then finding the coordinates of the corresponding point (-1, 0) on the unit circle. The value of cos 3pi is equal to the x-coordinate (-1). ∴ cos 3pi = -1.

What is the value of tan 3pi by 2?

What is the Value of Tan 3pi/2? The value of tan 3pi/2 is not defined. Tan 3pi/2 can also be expressed using the equivalent of the given angle (3pi/2) in degrees (270°). Since the tangent function is a periodic function, we can represent tan 3pi/2 as, tan 3pi/2 = tan(3pi/2 + n × pi), n ∈ Z.

What is the exact value of Tan 3pi 4?

Click to see full answer. People also ask, what is the value of tan 3pi 4? The exact value of tan(π4) tan ( π 4 ) is 1 . Secondly, what is the exact value of tan?

How to find the exact value of Cos?

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the second quadrant. The exact value of cos(π 4) cos ( π 4) is √2 2 2 2. The result can be shown in multiple forms.

What is the exact value of CSC 3pi 4?

Besides, what is the exact value of CSC 3pi 4? The exact value of csc(π4) csc (π 4) is √2. Why is tan 3pi 2 undefined? Since tan(theta)=y/x, whenever x=0 the tangent function is undefined (dividing by zero is undefined).

Which is the exact value of arctan ( π 4 )?

The exact value of tan(π 4) tan ( π 4) is 1 1. Multiply −1 – 1 by 1 1. The exact value of arctan(−1) arctan ( – 1) is − π 4 – π 4. The result can be shown in multiple forms.
