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:
1/10 times larger than 859,463
Step-by-step explanation:
The 5 is one digit behind the first number. And 500,000 × 1/10 = 50,000, which 50,000 is 1/10 smaller than 500,000.
