hi

i write the followinf code in maple

eq1:= f'''(x) - f'(x)

is this posible in maple that i worte the above command like this

Linear:= d3/d(x) - d/d(x)

eq1:= linear (f)

thanks for youe attention in advance

hi

i have 2 equation named eq1 and eq2 with 2 unknown parameter a and b which each equation dependent to a and b. i want to achieve critical a and b to minimize eq1 and eq2.

previously i have eq1 and one parameter a only and i use the NLPSOLVE command. but , for above mention problem i dont know how achieve a and b?

 

thancks for your attenrion in advance

hi

i have the following ode

.7246228659*(diff(f(x), x, x, x))+f(x)*(diff(f(x), x, x))+.6666666666-.6666666666*(diff(f(x), x))^2

with boundary conditions

f(0) = 0, D(f)(0) = a, (D(f))(b) = 1   (b corresponds to infinity and we can assume it 4 or 10 such that the solution converge)

i know the the solutions exist up to a critical value of "a" that beyonds no solution exist. for example for the following ode the critical value is...

Hi, i'm interested about parallel programming in maple but i cant find a good tutorial. is there anyone know a good refrence for this topic?

Hi,

I want to parallel the following code.it is good that part1 solved by one thread and part2 solved by other thread.

please help me.it must be noted that part1 and part 2 are independent "at each" iteration.

 

dtheta[m](x):= theta[m-1](x)+phi[m-1](x);
dphi[m](x):= theta[m-1](x)-2*phi[m-1](x);

for i from 2 by 1 to 10 do;

# part1

theta[i](x):=subs(m=i,dtheta[m](x)):
theta[i](x):=value(%):
eval(-theta[i](x),x=0);
