integrate the derivative of x^5
⇥Let's perform the differentiation: ddx(x5)
⇥ⓘ The derivative of xn is nxn -1: ddx(x5) = 5x4
⇥ 5x4
Let's integrate: ∫5x4dx
ⓘ A constant factor stays in front of the integral. An antiderivative of xn is xn + 1n + 1, for constant n with n ≠ -1: ∫5x4dx = 5·x55
5·x55
ⓘ Multiplying a fraction by a number multiplies its numerator: 5·x55 = 5x55■To simplify a fraction, divide its numerator and denominator by the same nonzero number: 5x55 = x5
x5
▶Indefinite integrals are defined up to an additive constant C, so this yields: x5 + C
