What is the exact value of sin 3pi?
0
The value of sin 3pi is equal to the y-coordinate (0). ∴ sin 3pi = 0.
What are the exact sine and cosine values for 3π 2?
The value of cos 3pi/2 is 0. Cos 3pi/2 can also be expressed using the equivalent of the given angle (3pi/2) in degrees (270°). Since the cosine function is a periodic function, we can represent cos 3pi/2 as, cos 3pi/2 = cos(3pi/2 + n × 2pi), n ∈ Z.
What is the exact value of tan 3pi 2?
The value of tan 3pi/2 is not defined. Tan 3pi/2 radians in degrees is written as tan ((3π/2) × 180°/π), i.e., tan (270°).
What is the value of sin 3 pi by 3?
Trigonometry Examples The exact value of sin(π3) sin ( π 3 ) is √32 .
How do you evaluate SEC 3pi 2?
Angle 3π2 corresponds to a point with coordinates (0,−1) on a unit circle. Therefore, cos(3π2)=0 . Since sec(3π2)=1cos(3π2) and cos(3π2)=0 , the value of sec(3π2) is undefined.
How do you solve sec 3pi 2?
Is 3pi 2 a rational number?
1 Answer. 3π is irrational.
What is half of 3pi 2 in radians?

Which of the following has the same value as sin 2pi 3?
Sin 2pi/3 is the value of sine trigonometric function for an angle equal to 2pi/3 radians. The value of sin 2pi/3 is √3/2 or 0.866 (approx).
What is the exact value of sec 2pi?
2π is a full rotation so replace with 0 . The exact value of sec(0) is 1 .
What is the value of all trigonometric functions?
Trigonometry values of different ratios, such as sine, cosine, tangent, secant, cotangent, and cosecant, deal with the measurement of lengths and angles of the right-angle triangle. The values of trigonometric functions for 0°, 30°, 45°, 60° and 90° are commonly used to solve trigonometry problems.
