what do RootOf(z2-z3-z1+_Z^3) mean?...

would like to solve for x in terms of z from z in terms of x

however, x2 = RootOf(z2-z3-z1+_Z^3) , what is _Z ?

ex1 := {z1=x1, z2=x3-x2^3, z3=-x1+x3, z4=-x1+x4};
solve({z1=x1, z2=x3-x2^3, z3=-x1+x3, z4=-x1+x4},{x1,x2,x3,x4})

{x1 = z1, x2 = RootOf(z2-z3-z1+_Z^3), x3 = z3+z1, x4 = z4+z1}

Hi,

Is it possible in Maple to output a complex number using j (or i) instead of I ?

thanks,

Hello,

I wish to enter in the math dot operator but I can't find the way to enter it in the document mod. I also searched the help and did not find a way.

Integration of a function with parameters...

I would like to see all the solutions for the following:

int(1/(a-(b+c)*t),t);

but the result only gives

(ln((-b-c)*t+a)/(-b-c)

For example, I can imagine that if b=-c in the integrand that the solution should be

t/a

and not undefined as it would be by substituting b=-c into the Maple result.

I tried

int(1/(a-(b+c)*x),x=0..t,AllSolutions);

but I didn't find that this gave the answer I was looking for either.
