hello all! I need a help to deduct the velocity boundary layer (for laminar flow) for a flat plate with the equations

boundary conditions:

u(x,0) = 0

v(x,0) = 0

u(x,infinite) = U => "U" is the free stream speed

u(0, y) = U

and found the Blasius solution:

Does anybody knows what I need to do? Thank you in advance.
