= ⁄ 3 Evaluate ∫[0, π/2] sin(x) dx.
∫[0, π/2] sin(x) dx = -cos(x) | [0, π/2]
Here are some common Riemann integral problems and their solutions: Evaluate ∫[0, 1] x^2 dx.
= -cos(π/2) + cos(0)
The Riemann integral of a function f(x) over an interval [a, b] is denoted by ∫[a, b] f(x) dx and is defined as the limit of a sum of areas of rectangles that approximate the area under the curve of f(x) between a and b. The Riemann integral is a way of assigning a value to the area under a curve, which is essential in calculus and its applications.
= lim(n→∞) (1/n^3) (n(n+1)(2n+1)/6)
: Using the definition of the Riemann integral, we can write:
: Using the logarithmic rule of integration, we can write:
