thanks.

my problem s i am not good in math.I shd learn maths n maple tool both.

okie thanks for your answers,

my eqn is

I[ds] = conjugate(mu[eff0])*C[ox]*W/L*(V[gb]-V[fb]-conjugate(phi[s])-gamma*sqrt(phi[s])+(1+1/2*gamma/sqrt(conjugate(phi[s])))*V[th])*V[dseff]

I would like to take Numerical Derivative w.r.t L i.e dIds/dL.

How I have to specify in maple12...?

I am new to this tool, when I read the manual I was confused.

Thanks

Equation:

I[ds] = conjugate(mu[eff0])*C[ox]*W/L*(V[gb]-V[fb]-conjugate(phi[s])-gamma*sqrt(phi[s])+(1+1/2*gamma/sqrt(conjugate(phi[s])))*V[th])*V[dseff];

this is my equation, I would like to take Numerical Derivative w.r.t (L) d(Ids)/dL..

once i right click the equation I am getting SOLVE option.

but to solve numerically...which option I have to select..?

thanks a lot

thanks man
