DEAR

MANY THANKS

@tomleslie 

Thank you

I did it

@tomleslie 

Many Thanks

but I  I need to use different Z, 

Z= 0.5,0.4,0.3,0.2,0.1,0

@tomleslie 

Thank you 

If I have this equation

U := (0.7638905680e-5*exp(.6891428810*Z)*cos(3.141592654*x)+0.1248528577e-4*exp(-.6891428810*Z)*cos(3.141592654*x)-0.2919729459e-1*exp(9.177422410*Z)*cos(3.141592654*x)-0.4253302728e-1*exp(-9.177422410*Z)*cos(3.141592654*x))*(1/10);
-0.1671841732

 and I need to use different Z, 

what I have to do?

Many thanks
