You have been asked to design a one-liter can shaped like a right circular cylinder. What dimensions will use the least material?

-I really need help on how to correctly plug this into my computer. Thank you in advance.

How to choose the integer parameters a, b, c, d, m to the following equation has two integer solutions?

sqrt(a* x + b) +  sqrt(c*x + d) = m. 

For example, the equation sqrt(x +5 ) + sqrt(8-x)=5 has two solution x = -1 and x = 4

1*2 Vector has nops should be 2

but

it show 3

Is it possible to use something like

Given an n*n matrix M an its rth row and cth column element m[r,c].Suppose m[r,c] = c*m[r-1,c]+a*m[r-1,c-1] and m[0,0]=1, m[0,k]=m[l,0]=0 for k>0,l>0.The letter "a" denotes a constant number and n can be any non negtive integer.

In 2D, graph a blue ellipse x(t)=3cos(t), y(t)=2sin(t) for 0≤t≤2∏. For t=0.5 graph a green tangent line to the ellipse and a red osculating circle. Also, give the curvature, the equation of the tangent line and the center of the osculating circle

Hi,

I have this system of lienar equations:

If I have the parameters-(v,k,lambda) of a combinatorical design, I wonder whether I can get the incidence matrix of the design or not with maple.

Remark:v is the number points of the design; k is the number of points on each line; lambda is the number of points common on every two lines.

Thanks!

Hi, I'm trying to find the first ten roots of the equation:

sin(a*Pi)*sqrt(4*a^2+3)*cos(sqrt(4*a^2+3)*Pi)+sin(sqrt(4*a^2+3)*Pi)*a*cos(a*Pi) = 0

But fsolve only finds one root, and not necessarily the first one. So I'm having a difficult time getting the first 10 roots without preknowledge of the intervals to search in. (I can obviously plot it, but there are some other parameters which affect this equation and I can't manually find the intervals every time I change them).

I've a problem with the buttons. It's not a problem to make a line break, but if I reload or change the text into my button (while the program ist running) maple/maplets ignores all line breaks.

Here is an small example (maybe not the best):

with(StringTools):
with(Maplets[Elements]): ToGreen := proc()
Maplets:-Tools:-Set(B(caption) = "blue\nhallo");
end proc:

maplet := Maplet([   

g1 := Vector([0, y, x]);

g2 := Vector([0, y^2-x-y, 0]);

g3 := Vector([x, x+y, 0]);

g4 := Vector([y, -y, 0]);

g5 := Vector([0, x*y+x/2+y/2, 0]);

g6 := Vector([0, x^2-x/4-y/4, 0]);

[g1, g2, g3, g4, g5, g6]

cc := [Vector(3, {(1) = 0, (2) = y, (3) = x}), Vector(3, {(1) = 0, (2) = y^2-x-y, (3) = 0}), Vector(3, {(1) = x, (2) = x+y, (3) = 0}), Vector(3, {(1) = y, (2) = -y, (3) = 0}), Vector(3, {(1) = 0, (2) = x*y+(1/2...

graph a red bezier curve start at the point P1(0, 0, 1) in the direction of <-2, 0, 1> and ends at P3=(0, 2, 0) from the direction of <0, 1, 0>. Use "axes=normal" and rotate the image for a good view of the curve. Also, write the coordinates of the other two control points that you used.
