Factor s^3-1. s3 − 1 s 3 - 1. Rewrite 1 1 as 13 1 3. s3 − 13 s 3 - 1 3. Since both terms are perfect cubes, factor using the difference of cubes formula, a3 −b3 = (a−b)(a2 + ab+b2) a 3 - b 3 = ( a - b) ( a 2 + a b + b 2) where a = s a = s and b = 1 b = 1. (s−1)(s2 +s⋅1+12) ( s - 1) ( s 2 + s ⋅ 1 + 1 2) Simplify. Tap for more steps...

$$\frac{(s+1)^3}{s^4} = \frac 1s + \frac 3{s^2} + \frac 3{s^3} + \frac 1{s^4}$$ and the inverse Laplace transform of each of those terms should be standard to you. After you've found it, it may be possible to simplify the answer!
Jul 25, 2017 · Explanation: note that. (x +a)3 = x3 + (a + a + a)x2 + (a.a + a.a + a.a)x +a3. (x −1)3 → a = −1. ⇒ (x − 1)3 = x3 +( −1 − 1 − 1)x2 + (1 +1 + 1)x +( −1)3. = x3 −3x2 +3x − 1.
Simpson's 1/3 rule, also simply called Simpson's rule, is a method for numerical integration proposed by Thomas Simpson. It is based upon a quadratic interpolation and is the composite Simpson's 1/3 rule evaluated for . Simpson's 1/3 rule is as follows: where is the step size for . The error in approximating an integral by Simpson's rule for is.
Oct 25, 2023 · Specifically, what does "one third" or 1/3 really mean? It seems simple on the surface, but there‘s actually a lot more nuance and usefulness to 1/3 than meets the eye! In this beginner‘s guide, we‘ll unpack the meaning of 1/3 from all angles – with plenty of examples and graphics to tie it all together.
