The Left Riemann Sum is a method for approximating the area under a curve by dividing the interval into equal subintervals and using the left endpoint of each subinterval to determine the height of the rectangle.
A method similar to Left Riemann Sum but uses the right endpoint of each subinterval to determine the height of rectangles.
A method that uses the midpoint between endpoints of each subinterval to determine rectangle heights.
An approximation method that uses trapezoids instead of rectangles to estimate area under a curve.
