Answer:
sin²x
Step-by-step explanation:
we have
(1 − cos x)(1 + cos x)=1-cos²x
Remember that
sin²x+cos²x=1 ------> i-cos²x=sin²x
therefore
(1 − cos x)(1 + cos x)=sin²x

Answer: We can cut <u>6</u> 
sections out of each piece of wood.
Step-by-step explanation:
Given: A piece of wood is 4 feet long.
Number of sections = 
![=4\times\dfrac{3}{2}\ \ \ \ [\because \dfrac{a}{b}\div\dfrac{c}{d}=\dfrac{a}{b}\times\dfrac{d}{c}]\\\\=2\times3\\\\=6](https://tex.z-dn.net/?f=%3D4%5Ctimes%5Cdfrac%7B3%7D%7B2%7D%5C%20%5C%20%5C%20%5C%20%5B%5Cbecause%20%5Cdfrac%7Ba%7D%7Bb%7D%5Cdiv%5Cdfrac%7Bc%7D%7Bd%7D%3D%5Cdfrac%7Ba%7D%7Bb%7D%5Ctimes%5Cdfrac%7Bd%7D%7Bc%7D%5D%5C%5C%5C%5C%3D2%5Ctimes3%5C%5C%5C%5C%3D6)
i.e. Number of sections = 6
Hence, we can cut <u>6</u> sections out of each piece of wood.
