Answer:
(g o f)(x) = (not simplified)
Step-by-step explanation:
(g o f)(x) = g(f(x))
g(x) = f(x) =
g(f(-5)) = g( =
=
g(-170) = =

Answer: sin = ±
Step-by-step explanation:
We very well know that,
cos2A=1−2sin²A
⟹ sinA = ±
As required, set A = & cos a=
,thus we get
sin =±
∴ sin =±
= ±
since ,360° < <450°
,180° < <225°
Now, we are to select the value with the correct sign. It's is obvious from the above constraints that the angle a/2 lies in the III-quadrant where 'sine' has negative value, thus the required value is negative.
hope it helped!
