1. the result of a mathematical integration; F(x) is the integral of f(x) if dF/dx = f(x) Adjective 1. existing as an essential constituent or characteristic; "the Ptolemaic system with its built-in concept of periodicity" "a constitutional inability to tell the truth" ...
1.An integral that is calculated between two specified limits, usually expressed in the form∫b/aƒ(x)dx.The result of performing the integral is a number that represents the area under the curve ofƒ(x)between the limits and thex-axis iff(x)is greater than or equal to zero between...

What is the integral of \frac{(x^4 + x^2+1)}{(1+x^2)}? What is the integral of 1/xsqrt(x(6-x))dx? What is the integral of x^1 from x=4 to x=7? What is the integral from __0__ to __2__ of \frac{dx}{(x^2-6x+5)} What is the integral of 9 - x^2 fro...
Examples of Improper Integrals ∫0∞cos(x)dx=limt→∞∫0tcos(x)dx=limt→∞[sin(x)|0t=limt→∞sin(t)−0 Take for instance the integral,∫−44116−x2dxwhich corresponds to figure 6. The endpoints look like discontinuities, so some limits are needed to evaluate the integral.=limt→...
Here is my idea. First we will consider the following two integrals: I=∫π20x2√tanxdx;J=∫π20x2√cotxdx ⇒I=12((I−J)+(I+J)) Thust we need to evaluate the sum and the difference of those two from above. I also saw from here that the "sister" integral di...
∫dxf(x)∫dxf(x) is not equal to ln|f(x)|+Cln|f(x)|+C. If you differentiate ln|f(x)|ln|f(x)|, you'll notice that you get f′(x)f(x)f′(x)f(x). It is precisely because you have a 11−x2√11−x2 that you do get the natural logarithm of an arcsine...
The CTOD value, δ, is a physical measure of the real crack tip opening. The tougher the material the more opening of the crack mouth will occur before fracture. Normally it is not possible to measure CTOD directly at the crack tip; therefore clip gauges are positioned at a distance from...
Definite integrals are a type of integral wherein the integration is done within a defined interval. The interval can be either open or closed, as long as one is present. Unlike indefinite integrals, where the answers are functions, the answers to definite integrals have actual values. The ...
