(1-sinx+cosx)^2 = 2(1+sinx)(1+cosx)​
bogdanovich [222]

If you're trying to establish an identity, the given equation is not an identity. The proper identity would be as follows:

(1 - sin(<em>x</em>) + cos(<em>x</em>))² = (1 - sin(<em>x</em>))² + 2 (1 - sin(<em>x</em>)) cos(<em>x</em>) + cos²(<em>x</em>)

… = (1 - 2 sin(<em>x</em>) + sin²(<em>x</em>)) + 2 (1 - sin(<em>x</em>)) cos(<em>x</em>) + cos²(<em>x</em>)

… = 2 - 2 sin(<em>x</em>) + 2 (1 - sin(<em>x</em>)) cos(<em>x</em>)

… = 2 - 2 sin(<em>x</em>) + 2 cos(<em>x</em>) - 2 sin(<em>x</em>) cos(<em>x</em>)

… = 2 (1 - sin(<em>x</em>) + cos(<em>x</em>) - sin(<em>x</em>) cos(<em>x</em>))

… = 2 (1 - sin(<em>x</em>) + cos(<em>x</em>) (1 - sin(<em>x</em>)))

… = 2 (1 - sin(<em>x</em>)) (1 + cos(<em>x</em>))

But if you're trying to solve an equation:

(1 - sin(<em>x</em>) + cos(<em>x</em>))² = 2 (1 + sin(<em>x</em>)) (1 + cos(<em>x</em>))

2 (1 - sin(<em>x</em>)) (1 + cos(<em>x</em>)) = 2 (1 + sin(<em>x</em>)) (1 + cos(<em>x</em>))

(1 - sin(<em>x</em>)) (1 + cos(<em>x</em>)) - (1 + sin(<em>x</em>)) (1 + cos(<em>x</em>)) = 0

(1 + cos(<em>x</em>)) (1 - sin(<em>x</em>) - 1 - sin(<em>x</em>)) = 0

-2 sin(<em>x</em>) (1 + cos(<em>x</em>)) = 0

sin(<em>x</em>) = 0   <u>or</u>   1 + cos(<em>x</em>) = 0

sin(<em>x</em>) = 0   <u>or</u>   cos(<em>x</em>) = -1

[<em>x</em> = arcsin(0) + 2<em>nπ</em>   <u>or</u>   <em>x</em> = arcsin(0) + <em>π</em> + 2<em>nπ</em>]   <u>or</u>

… [<em>x</em> = arccos(-1) + 2<em>nπ</em>]

We have arcsin(0) = 0 and arccos(-1) = <em>π</em>, so the solution set reduces to

<em>x</em> = 2<em>nπ</em>   <u>or</u>   <em>x</em> = (2<em>n</em> + 1)<em>π</em>

(where <em>n</em> is any integer)

Kate made a box to hold her jewelry collection. She used 42 inches of wood to build the sides of the box. If the box was 9 Inche
antoniya [11.8K]
We can use the 9 inches wide to determine that 18 inches of the 42 inches are the wide sides. 42 - 18 = 24, so we divide 24 by how many long sides there are, 2. 24 ÷ 2 = 12. The box was 12 inches long.
