## 3D Cube...

Maple

I got my 8 coordonates, I wanna plot a cube. When I all my coords in pointplot3d, it connects p1 to p2 to p3 ..to p8 so it doesn't make a cube. How do I make it so it connects the coords I want to make the cube. Thank you

## Kirchhoff and linear systems...

Maple

I need to find I1 to I9. I need to find this using the Kirchhoff's Current Law and Kirchhoff's Voltage Law. ( we haven't seen yet what both of these laws are)

## Magic square...

Maple

I need to create a magic square of order n=4 using a Matrix.

I have tried many linear equations system. Got me nowhere so far.

## Air minimal between 2 curves [0,1], Answ...

Maple
For which value of c is the area between f(x) and g(x) minimal?  f(x) and g(x) are both continuous   ( in the interval [0,1] )

> g := x-> piecewise(0<=x and x<=c, m1*x+b1, c<x and x<=1, m2*x+b2);

f := x-> x^3;

## Integers...

Maple

I need to do the integral of a certain function by using

a) Rectangles method

- Would it be sum(f,x=a..b,n) ?

b)Trapezoid method ( I can not use trapezoid() )

c)Simpson's method ( I can not use simpson() )

I know how to do them without Maple, but with Maple I have no idea.
