0.2588190
The value of cos 5pi/12 is 0.2588190. . .. Cos 5pi/12 radians in degrees is written as cos ((5π/12) × 180°/π), i.e., cos (75°).
How do you find the exact value of sin 5pi 4?
Sin 5pi/4 can also be expressed using the equivalent of the given angle (5pi/4) in degrees (225°). ∴ sin 5pi/4 = sin 5π/4 = sin(225°) = -(1/√2) or -0.7071067. . . Explanation: For sin 5pi/4, the angle 5pi/4 lies between pi and 3pi/2 (Third Quadrant).
How do you solve Tan 5pi 6?
Explanation: For tan 5pi/6, the angle 5pi/6 lies between pi/2 and pi (Second Quadrant). Since tangent function is negative in the second quadrant, thus tan 5pi/6 value = -1/√3 or -0.5773502. . . Since the tangent function is a periodic function, we can represent tan 5pi/6 as, tan 5pi/6 = tan(5pi/6 + n × pi), n ∈ Z.
What is the value of Cosπ?
-1
The value of cos pi is -1. Cos pi can also be expressed using the equivalent of the given angle (pi) in degrees (180°). Since the cosine function is a periodic function, we can represent cos pi as, cos pi = cos(pi + n × 2pi), n ∈ Z.
What is the exact value of cos 5π 3 )?
The value of cos 5pi/3 in decimal is 0.5. Cos 5pi/3 can also be expressed using the equivalent of the given angle (5pi/3) in degrees (300°). Since the cosine function is a periodic function, we can represent cos 5pi/3 as, cos 5pi/3 = cos(5pi/3 + n × 2pi), n ∈ Z.
