Note: This only works when \(x\) is measured in radians. We are now going to look at more complex trigonometric functions where we will use the general rule: \(\int ...

In other words you add one to the power, divide by the new power and also by the derivative of what's inside the bracket. Don't forget to add the constant of integration.

Abstract When generalized harmonic functions belong to the weighted Lebesgue classes, we give the asymptotic behaviors of them at infinity in an n-dimensional cone. Meanwhile, the integral ...

Abstract The main object of this paper is to give sufficient conditions for certain families of integral operators, which are defined here by means of the normalized form of the generalized Bessel ...

被积函数$f(x,y)$作为曲顶柱体在点$(x,y)$处柱体微元的高，用底面积$\textrm{d}\sigma>0$乘上高$f(x,y)$就得到一个小柱体体积 ...
