Factor and simplify the expression.
1-sin^3 x
as a difference of cubes it would be
(1-sinx)(1 + sinx + sin^2x)
but I don't see any "simplification"
Sure, I can help you with that! It seems like we need to factor and simplify the expression 1 - sin^3(x).
Let's rewrite the expression using the identity sin^3(x) = (sin(x))^3:
1 - (sin(x))^3
Now, we can factor this expression as follows:
(1 - sin(x))(1 + sin(x) + (sin(x))^2)
And there you have it! The expression 1 - sin^3(x) can be factored as (1 - sin(x))(1 + sin(x) + (sin(x))^2). However, since we can't simplify it further, you can now go ahead and use this factorization as needed.
To factor and simplify the expression 1 - sin^3(x), we can use the identity a^3 - b^3 = (a - b)(a^2 + ab + b^2).
In this case, a = 1 and b = sin(x). Applying the identity, we have:
1 - sin^3(x)
= 1^3 - sin^3(x)
= (1 - sin(x))(1^2 + 1(sin(x)) + sin^2(x))
= (1 - sin(x))(1 + sin(x) + sin^2(x))
Therefore, the factored and simplified expression for 1 - sin^3(x) is (1 - sin(x))(1 + sin(x) + sin^2(x)).
To factor and simplify the expression 1 - sin^3 x, we can use the identity
a^3 - b^3 = (a - b)(a^2 + ab + b^2).
In this case, a = 1 and b = sin x. Thus, we can rewrite the expression as
1 - sin^3 x = (1 - sin x)(1 + sin x + sin^2 x).
To simplify further, we can use the identity
sin^2 x + cos^2 x = 1.
Rearranging this identity gives us sin^2 x = 1 - cos^2 x.
Substituting sin^2 x = 1 - cos^2 x into the expression, we have
(1 - sin x)(1 + sin x + sin^2 x)
= (1 - sin x)(1 + sin x + (1 - cos^2 x))
= (1 - sin x)(2 - cos^2 x)
= 2(1 - sin x) - cos^2 x(1 - sin x)
= 2 - 2sin x - cos^2 x + cos^2 x sin x
= 2 - 2sin x - (1 - sin^2 x) + cos^2 x sin x
= 2 - 2sin x - 1 + sin^2 x + cos^2 x sin x
= 1 + sin^2 x - 2sin x + cos^2 x sin x
= (1 - sin x)^2 + cos^2 x sin x.
Thus, the expression 1 - sin^3 x is factored and simplified as (1 - sin x)^2 + cos^2 x sin x.
