I am trying to solve the system of equation by maple but its not giving the correct answer.

> e1 := (1/2)*alpha*alpha[3]^2*q[2]^3-V*alpha[4]*q[2]^2-V*alpha[0]+(1/2)*alpha*alpha[0]^2+(1/2)*alpha*alpha[1]^2*q[2]+(1/2)*alpha*alpha[2]^2*q[2]^2+(1/2)*alpha*alpha[4]^2*q[2]^4-V*alpha[2]*q[2]+C+alpha*alpha[3]*q[2]^2*alpha[1]+alpha*alpha[4]*q[2]^3*alpha[2]+alpha*alpha[4]*q[2]^2*alpha[0]+alpha*alpha[2]*q[2]*alpha[0];
> e2 := -gamma*alpha[2]*q[3]*q[2]^2+2*beta*alpha[4...

I want to solve a diff eqn, but it is giving absurd answer.

> ode := diff(f(x), x, x) = (Phi(x)-lambda)*f(x);
                    d  / d      \                         
                   --- |--- f(x)| = (Phi(x) - lambda) f(x)
                    dx \ dx     /                         
> dsolve(ode);
               / /                           / d  / d       \\\          \
   f(x) = DESol|{ (-Phi(x) + lambda) _Y(x) + |--- |--- _Y(x)|| }, {_Y(x)}|

I am solving a system of equation, and whenever I used the "solve" command, its showing "Warning, solutions may have been lost", The system of equation is like that, Pls help as soon as possible.

e1 := (1/2)*alpha[2]^2+6*delta*alpha[2];

e2 := alpha[2]*alpha[1]+delta*(10*alpha[2]*lambda-20*alpha[2]*d+2*alpha[1]);

e3 := -V*alpha[2]+(1/2)*alpha[1]^2+alpha[2]*alpha[0]+delta*{8*alpha[2]*(d^2-lambda*d+mu)+3*alpha[1]*(lambda-2*d)+(4*alpha[2]*lambda-8*alpha[2]*d)*(lambda-2*d)};
