LearnPracticeDownload Tan 5pi/6 The value of tan 5pi/6 is -0.5773502. . .. Tan 5pi/6 radians in degrees is written as tan ((5π/6) × 180°/π), i.e., tan (150°).
How do I find the value of sin 5PI/6?
How do I find the value of sin 5pi / 6? Another way to think about it is to draw the angle in a Unit circle and create the "new" triangle in Quadrant II. Drop a perpendicular to the x-axis and you will have the correct triangle to use. From this triangle, you need the opposite leg length, which is 1 2.
What is the value of 5pi/6 radians in degrees?
⇒ 5pi/6 radians = 5pi/6 × (180°/pi) = 150° or 150 degrees ∴ cos 5pi/6 = cos 5π/6 = cos(150°) = −√3/2 or -0.8660254. . .
What angle is 5pi 6?
=5π6⋅180π=5⋅30=150 degree.
What is cos 5pi 6 as a fraction?
∴ cos 5pi/6 = cos 5π/6 = cos(150°) = −√3/2 or -0.8660254. . . Explanation: For cos 5pi/6, the angle 5pi/6 lies between pi/2 and pi (Second Quadrant). Since cosine function is negative in the second quadrant, thus cos 5pi/6 value = −√3/2 or -0.8660254. . .
