Learn how to easily calculate the volume of a solid of revolution using a simple formula from elementary school. Discover the method through an example of calculating the volume of a sphere formed by rotating a curve around an axis, without complex integrals.
Definite integrals can be calculated with respect to variable x or y, and sometimes should be, if it’s more convenient. This often plays a big role in the applications of integrals, such as calculating the areas of regions, arc lengths, volumes, and surface areas of solids of revolution. Often we don’t even have a choice, because the conditions of the problem specify that the curve rotates around the OY axis, not the OX. How do you do that?
Discover how to effectively change integration limits by substitution in definite integral tasks. This article explains in detail the step-by-step process of changing limits, using real examples and formulas to simplify understanding of this crucial mathematical technique.
Wondering why you get different results from those listed in the textbook when solving indefinite integrals? Learn how different integration methods and adding a constant can affect the outcomes and how to correctly interpret these differences.
Learn how to effectively use the substitution method in solving indefinite integrals. This article contains detailed tips and examples that will help you understand when and which substitutions to choose to simplify difficult integrals. Ideal for mathematics students starting their journey in integration, looking for practical advice and solutions.
