## How to solve a set of nonlinear equation...

Maple

Hi,

I want to solve a set of equation (four equations) to plot variation of u[i10],u[i20],phi[d0] versus delta[d] for delta[i]=0.5 and different values of alpha (for example, alpha=0, 0.1,0.2)

How can I do that with Maple?

(It should be noted that depending on the sign of phi[d0], one must use Eq. 2a or 2b. The other equations are Eqs. 1,3,4)
I expect to plot figures like the attached figure.

## ‘csgn’ in an expression...

Maple 2018

Hi,

I need taylor expasion of

A(w):=M/sqrt(M^2+2*w)-mup*sqrt(((mu*M^2+3*sigmap-2*w)-sqrt((mu*M^2+3*sigmap-2*w)^2-12*mu*sigmap*M^2))/(6*sigmap))

I used taylor(A,w,4), but I had a problem!

If I know that A(w) is a real function, how can I remove ‘csgn’ from the  ‘taylor(A,w,4)’ command:

Thanks.
