WebDec 23, 2024 · The width of this rectangle is d x, where by d x we mean some tiny distance measured along the x axis. We make d x small enough that y ( x) can be taken as constant over the width of the rectangle. So the area of this rectangle is then just: d A = y ( x) d x. Then the area under the whole curve is just the sum of the areas of all these tiny ... WebWhen calculating the area under the curve of f ( x), use the steps below as a guide: Step 1: Graph f ( x) ’s curve and sketch the bounded region. This step can be skipped when you’re confident with your skills already. Step 2: Set the boundaries for the region at x = a and x = b. Step 3: Set up the definite integral. median household income singapore 2022
