These are questions asked by GWANWOO

what means the command that `linsolve` and 

when

a:=matrix([[a1,a2],[b1,b2]])

b:=vector([c1,c2])

c:=transpose(a)

linsolve(c&*a,c&*b)

&* <<--- what is it

 

i want to make a solution that makes sphere not using Sphereplot()

i mean it`s fomula for a sphere that x^2+y^2+z^2=r^2

but, as you know

if i do like this

plot3d(x^2+y^2+z^2,x=0..1,y=0..1)

Warning, expecting only range variables [x, y] in expression x^2+y^2+z^2 to be plotted but found name z

 

how to make a sphere !?

with(plots);

polarplot(1+2*sin(theta),theta=0..2*Pi);

 

it makes a graph made up of polar coordinate.

i wannna solve the question in cartesian coordinate

i wouldnt come up with ideas to solve it!!

please help me

 

for example)

y= r*sin(theta)

1+2y/r=r

y=(r^2-r)/2

...

...

y=x^n+x^n ....

x= something , something, something

 

 

i asked it to show explanations

and got an solution about that, but it doesnt work in my Maple

i wanna know what do i wrong , why it`s not working right
