What quadrant does 3pi 4 lie in?
The angle is in the second quadrant.
What is 3pi 4 reference angle?
For −3π4 , it will look like this. (Note that if your angle is positive, it will start from 0 and turn anticlockwise, if your angle is negative, it will start from 0 and turn clockwise.) So, the reference angle is the angle between the terminal side and the x-axis. Lets find out that angle. And the reference angle is π …

How do you find the reference angle for 1406?
Calculus Examples Find an angle that is positive, less than 360° , and coterminal with 1406° . Subtract 360° 360 ° from 1406° 1406 ° . The resulting angle of 1046° 1046 ° is positive and coterminal with 1406° 1406 ° but isn’t less than 360° 360 ° . Repeat the step.
In which quadrant does the terminal side of a 7π 4 radian angle in standard position lie?
fourth quadrant
The angle is in the fourth quadrant.
How do you solve cos3pi?
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 3π in degrees?
540∘
⇒ 3π radians = 3×180∘ = 540∘
How do you find sin cos and tan of 3pi 4?
1 Answer
- sin(3π4)=√22.
- cos(3π4)=−√22.
- tan(3π4)=−√22.
How do you find the reference angle?
In order to find its reference angle, we first need to find its corresponding angle between 0° and 360°. This is easy to do. We just keep subtracting 360 from it until it’s below 360. For instance, if our angle is 544°, we would subtract 360° from it to get 184° (544° – 360° = 184°).
