∫abf(x) dx = F(b) − F(a)
∫ab[αf(x) + βg(x)] dx = α∫abf(x) dx + β∫abg(x) dx
∫abf(g(x))g′(x) dx = ∫g(a)g(b)f(u) du
说明: 令u=g(x),则du=g’(x)dx.
∃c ∈ [a, b], ∫abf(x) dx = f(c)(b − a)
∫0π/2sin x dx = 1
∫abf(x) dx = F(b) − F(a)
∫ab[αf(x) + βg(x)] dx = α∫abf(x) dx + β∫abg(x) dx
∫abf(g(x))g′(x) dx = ∫g(a)g(b)f(u) du
∃c ∈ [a, b], ∫abf(x) dx = f(c)(b − a)
∫0π/2sin x dx = 1
