Something some of us may have forgotten how to do: LRAM Steps: -first you must create a number line with each of the bounds as the end points then you should put markers on the time line for each significant number between the bounds -the next step is to draw a specific number of rectangles as specified by the given n= across the numberline resembeling a bar graph you must -then plug in each significant number into the given equation plug those results into the rectangles to serve as the height of the rectangle -then you must decipher what the width would be considering the number of rectangles needed in relation to the bounds. -then you will multiply each of the widths by the heights to get multiple solutions which you will add together to get the area of the bounded region -keep in mind that for lram you will multiply all widths by heights except for that of the last rectangle. RRAM Steps: -first you must create a number line with each of the bounds as the end points -then you should put markers on the time line for each significant number between the bounds -the next step is to draw a specific number of rectangles as specified by the given n= across the numberline resembeling a bar graph -you must then plug in each significant number into the given equation plug those results into the rectangles to serve as the height of the rectangle -then you must decipher what the width would be considering the number of rectangles needed in relation to the bounds. -then you will multiply each of the widths by the heights to get multiple solutions which you will add together to get the area of the bounded region -keep in mind that for Rram you will multiply all widths by heights except for that of the first rectangle. TRAM Steps: -first you must create a number line with each of the bounds as the end points -then you should put markers on the time line for each significant number between the bounds -the next step is to draw a specific number of trapezoids as specified by the given n= across the numberline resembeling a bar graph -you must then plug in each significant number into the given equation plug those results into the trapezoids to serve as the width of the trapezoid -then you must decipher what the height would be considering the number of rectangles needed in relation to the bounds. -then you will plug in each of the numbers from the widths and heights into 1/2(b1+b2) to then get multiple solutions and then add the solutions all together to get the area when using the trapezodial rule.
