Answer:
cos 2 x=1-sin^2 x
Step-by-step explanation:
x=-135°
cos 2x=cos (-270)=cos (-270+360)=cos 90=0
or cos 2x=1-2sin ²x=1-2(sin (-135))²
=1-2(-sin 135)²
=1-2(sin 135)²
=1-2(sin (180-45))²
=1-2(sin²45)
=1-2 (\frac{1}{\sqrt{2}})²
=1-1
=0
Answer:
are this if its a function or not?
Step-by-step explanation:
1. 4^2 = 16
2. 32/16 = 2
3. 2*3 = 6
4. 17-6=11
5. 11 + 6 = 17
The answer is 17
