another problem i worked half way on and stuck on
ODE is dx/dt = x^(3/4)
i need to find values for constans a > 0 and b or which x(t) = (at)^b is a solution of the ODE or t>0. Is this function also a solution for t<0?
ok, so here goes my crazy method in doing this..
x'(t) = ba(at)^(b-1)
put this into the ODE:
ba(at)^(b-1) = ((at)^b)^3/4
now what?.. no initial conditions are given. how do they expect us to find a and b =S and..... determine t? =| that looks crazy.. how you obtain a,b,t from that equation
