Mathematica will not integrate with a constant [closed]
I don't know what is wrong, Mathematica will only give me the original integral but won't evaluate it. any help?
eq1 = 0.048519*x
eq2 = -0.0134
eq3 = {sin[(n*[CapitalPi]*x)/0.586667]}
eq4 = ...

Integrating with vector coefficients in Maple
I'm trying to use Maple to do something like this integral:
$\displaystyle\int \frac{a\mu-b}{||a\mu-b||^3} \mathrm{d}\mu$
Where $a, b$ are vectors and $\mu$ is a scalar I'm integrating by. But I ...

can't figure out what I been doing wrong on simple integration question
$$\int_0^1 \sqrt{(\sqrt{5})^2+(2t)^2}\;dt$$
Based on the formula
$\int \sqrt{a^2+x^2}\;dx=\frac{1}{2}[x\sqrt{a^2+x^2}+a^2\log(x+\sqrt{a^2+x^2})]$
I just plug in above input into the formula above

Automated generation of a parametric plot?
Currently we are introducing integrals of manifolds in $3d$-Space in a course. We are given some set $E \subset \mathbb{R}^3$ and should evaluate the surface and scetch how it looks.
For example ...

Taking advantage of linearity of integration in Mathematica
I want to evaluate an integral of form given below
$$\int\limits_\alpha^\beta (f(x) + g(x) + h(x) + ...) dx$$
When I give it to Mathematica it takes forever to evaluate. But if I give it in this ...
