Consider the function {{MATH_229}} on the interval {{MATH_230}}. We will approximate the area between the graph of {{MATH_231}} and the {{MATH_232}}-axis on the interval {{MATH_233}} using a {{CMD_234}}right {{CMD_235}}Riemann sum with {{MATH_236}} rectangles. First, determine the width of each rectangle. {{MATH_237}} Next, we will determine the grid-points.
