= ln(2) - ln(1)
: Using the logarithmic rule of integration, we can write:
: Using integration by parts, we can write: riemann integral problems and solutions pdf
∫[0, π/2] sin(x) dx = -cos(x) | [0, π/2]
= ln(2)
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.
