What value of sin is 2 3?
For sin 2pi/3, the angle 2pi/3 lies between pi/2 and pi (Second Quadrant). Since sine function is positive in the second quadrant, thus sin 2pi/3 value = √3/2 or 0.8660254. . .
What quadrant is sin theta 2 3?
Precalculus Examples Evaluate arcsin(23) arcsin ( 2 3 ) . The sine function is positive in the first and second quadrants.
What is the value of sin theta by 2?
The half angle formula: sin(θ/2) =± √((1-cosθ)/2). Therefore, (1-cosθ)/2 = (1+. 6)/2 = . 8.
How do you evaluate sin 3pi 2?
The value of sin 3pi/2 can be calculated by constructing an angle of 3π/2 radians with the x-axis, and then finding the coordinates of the corresponding point (0, -1) on the unit circle. The value of sin 3pi/2 is equal to the y-coordinate (-1). ∴ sin 3pi/2 = -1.
Which of the coordinates is equal to cos 2pi 3?
The value of cos 2pi/3 is equal to the x-coordinate (-0.5).
What angle is 3pi 2?

How do you solve sin 3pi?
The value of sin 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 sin 3pi is equal to the y-coordinate (0). ∴ sin 3pi = 0.
Which of the following best explains why cosine of 2pi 3 does not equal cosine of 5pi 3?
Which of the following best explains why cosine of (2pi/3) DOES NOT equal cosine of (5pi/3)? Cosine is negative in the second quadrant and positive in the fourth quadrant.
What is the value of sin 3 theta?
Hence, the answer is nπ,(2n+1)4π.
What is sin theta equal to?
As per the sin theta formula, sin of an angle θ, in a right-angled triangle is equal to the ratio of opposite side and hypotenuse. The sine function is one of the important trigonometric functions apart from cos and tan.
