  2. Integral of secant cubed - Wikipedia

    en.wikipedia.org/wiki/Integral_of_secant_cubed

    This is one of several integrals usually done in a first-year calculus course in which the most natural way to proceed involves integrating by parts and returning to the same integral one started with (another is the integral of the product of an exponential function with a sine or cosine function; yet another the integral of a power of the ...

    In particular, it can be used to evaluate the integral of the secant cubed, which, though seemingly special, comes up rather frequently in applications. [ 1 ] The definite integral of the secant function starting from 0 {\displaystyle 0} is the inverse Gudermannian function , gd − 1 . {\textstyle \operatorname {gd} ^{-1}.}

    en.wikipedia.org/wiki/Differentiation_of_integrals

    In mathematics, the problem of differentiation of integrals is that of determining under what circumstances the mean value integral of a suitable function on a small neighbourhood of a point approximates the value of the function at that point.

    On the other hand , just because a stock has declined is no reason to sell, either. In fact, it may be a reason to buy more if your original reasons for buying the stock is still intact.

  7. Integral equation - Wikipedia

    For example, one method of solving a boundary value problem is by converting the differential equation with its boundary conditions into an integral equation and solving the integral equation. [1] In addition, because one can convert between the two, differential equations in physics such as Maxwell's equations often have an analog integral and ...

    A ray through the unit hyperbola = in the point (,), where is twice the area between the ray, the hyperbola, and the -axis. The earliest and most widely adopted symbols use the prefix arc-(that is: arcsinh, arccosh, arctanh, arcsech, arccsch, arccoth), by analogy with the inverse circular functions (arcsin, etc.).
