1. ### Evaluate using u-substitution?

Since u = x + 1, du = dx and x = u - 1. Bounds: If x = 0, then u = 0 + 1 = 1. If x = 1, then u = 1 + 1 = 2. Therefore, ∫(x = 0 to 1) x^2 √(x + 1) dx = ∫(u = 1 to...

2. ### Evaluate using u-substitution?

∫ (x²)√(x + 1) dx = ? Let u = x + 1. Then: du/dx = 1 du = dx And (subtracting 1 from...)√(u) – 2u√(u) + √(u)] du = ∫ [u^(5/2) – 2u^(3/2) + u^(1/2)] du = (2/7)u^(7/2) – 2(2/5)u^(5/2) + (2/3)u^(3/2) + C = (2/7)u^(7/2) – (4/5)u...
