26 Σεπ 2022 · Derivatives find instantaneous rates of change. By contrast, integrals find areas under curves. The integral symbol \int ∫ is derived from the word “sum.”. To estimate the area under the curve, we can approximate the curve using rectangles and compute the sum of their area, as pictured below.
Indefinite Integrals Rules: ∫Integration By Parts: ′= −∫ ′ ∫Integral of a Constant: ( ) 𝑥=𝑥⋅ ( )
If the curves intersect then the area of each portion must be found individually. Here are some sketches of a couple possible situations and formulas for a couple of possible cases.
Calculus: Integrals, Area, and Volume. Notes, Examples, Formulas, and Practice Test (with solutions) Topics include definite integrals, area, “disc method”, volume of a solid from rotation, and more.
In practice, definite integrals (and areas) are evaluated using the following deep result, which is at the heart of calculus, relating di˙erential and integral calculi, or else tangent line and area computation.
