I have coded maple script and got that error. How can I fix it?

Here is my code Please help.



I have two complex functions with 3 variables: z1,z2,t . I need the first derivative of one of these functions with respect to one variable onle. Here is what I did:



diff(f1,z1(t)) this gives me an error. I need to write the variable as z1(t) not z1 because I'm doing some calculations for different time.

Thanks for the help.

I am solving ode system in double precesion with digits 16, some results are in power of -16 which are equivalent to zero. How can I ask maple to put any number with the power of -16 or less to be zero?

Thx for the help.

How can I specify the step size in solving complex system of ordinary differential equations using RK45 with dsolve command???


Oops! you are right, thanks. How if the equations like these




where f1 and f2 are same as in the previous post.

The results are not explicit. How can we fix it?

Thanks again
