The correct answers are:

a) sin (4π/3) = $- \frac{ \sqrt{3} }{2}$
b) cos (5π/6) = $- \frac{ \sqrt{3} }{2}$

I hope this helps.

The normal body temperature of a camel is 37 degrees Celsius the temperature varies by up to three degrees C throughout the day.

natta225 [31]

The normal body temperature : to = 37° C
An inequality is:
| t - to | ≤ 3
| t - 37 | ≤ 3
t - 37 ≤ 3     AND ( - t - 37 ) ≤ 3
t ≤ 3 + 37               - t + 37 ≤ 3
t ≤ 40                     - t ≤ 3 - 37
                              - t ≤ - 34   / * ( - 1 )
                                t ≥ 34
Answer t ∈ [ 34°C, 40° C ].

Reference angle for -19pi/6?

kow [346]

$\bf \cfrac{19}{6}\implies 3+\cfrac{1}{6}
\\ \quad \\\\
\cfrac{-19\pi }{6}\implies -\left(3\pi +\cfrac{1\pi }{6} \right)\impliedby clockwise
\\ \quad \\\\
or\implies -\left(2\pi +\pi +\cfrac{\pi }{6} \right)$

go that much "clockwise", you'll end up at the 2nd quadrant,
the reference angle, is its reflective angle on the 1st quadrant
