Answer:
Cos 2x+sin x = cos x cos x - sin x sin x + sin x
Step-by-step explanation:
Cos 2x+sin x
use Trigonometric identities.
cos (2x) = cos (x + x) = cos x cos x - sin x sin x
I think it's the 3rd one
because it makes sense
where is the as shown below?
#1
x intercept is -5
y intercept is -5
#2
y=8x
