Tan 5pi 6
What is the correct value of tan (5pi / 6)? 3
Here are the cices:
A. Three times the square root of three
B. The negative square root of three times three
Vs. 1/2
Divide D. 2 by the negative square root 2
Thanks .. please explain briefly ..
Tan (5 ft / 6) = Tan (urine / 6)
= Tan (pi / 6) ..... (bcos tan is negative in the second quadrant)
= 1 / square 3
= Square 3/3, i.e. (b)
This is B-neg. Three times the square root of 3. Because if you look at the circle of the unit, the x coordinate is 1/2 and the y coordinate is 3 times 2 square root. If you split (to be brown) you will get a negative. . 3 out of 3 square root.
Tan 5pi 6
Tan 5pi 6
5
5/6 is equal to 150 degrees.
If you draw the circle of the unit and see that the special triangle can represent 150 degrees 30 degrees (reference angle) in 306090, then the answer to tan (5 € / 6) is 1 š3 or. Is [3] / 3.
This is negative because, according to CAST rules, tan [x] is negative in the second quadrant, where 150 degrees.
[Answer: b]
Reference angle is 180/6 = 30 degrees.
Light brown (30) = 1 / square (3)
5pi / 6 is in square 2. And the negative ent is in quadrant 2.
So the answer is 1 / sqrt (3) or sqrt (3) / 3 if you argue
Yeah Al that sounds pretty crap to me, Looks like BT aint for me either.
Tan (€ 5/6)
(€ 5/6) is in Quadrant II.
Ten is negative in Quadrant II, so your answer would be negative.
It has a reference angle (ÃÂ € / 6) which you can enter as 3/3. Need to know
B. 3/3
Well, I give up ... why do they all get the right answer?
Then (5 € / 6) = then (€ € Â € / 6)
= Chocolate (6/6)
= 1 / ˆ3
= 3/3
(B)
Tan 5pi 6
Tan 5pi 6
tan (x) = sin (x) / cos (x)
Sin (5 ft / 6) = 1/2
cos (5pi / 6) = square (3) / 2
sin / cos = 1/2 * 2 / sqrt (3)
= 1 / square (3)
= Square root (3) / 3
Then b.
