## Fouier series , plotting first 50 terms...

Maple

Hi, a school question asked me to plot 50 terms of below fourier series. I need some help programming this plz.

(4/pi)*sum (sin (2k-1)*x/(2k-1), k=1..infinity) (k+1,k=0..n)

## Jacobian not showing for Lorenz equation...

Maple 2019

I am trying to get jacobian computed for lorenz equations, not showing matrix, using Maple 2019 newest version. any guidance?

## triple integral question...

how can I solve triple integral below in maple, thanks

## 3d plot spherical coordinates...

Maple 2019

I'm trying to create an ellipsoid using spherical coordinates.

"x^2 + y^2/4 + z^2/9 = 1" how can I enter this?

This is what I have , but shape show up really crazy

plot3d([cos(theta)*sin(phi),sin(theta)*sin(phi),cos(phi)],theta=0..2*Pi,phi=0..Pi,scaling=constrained,axes=boxed);

Thanks

[An edited and reposted version of this Question, which has subsequently been deleted, specifically asked that the plot be done by making a small adjustment to Maple's spherical coordinates. The deleted version also named the ellipsoid E, a detail which is important for understanding correctly the OP's subsequent integration Question. --Carl Love acting as a Moderator]
