Regards,

I am trying to solve a problem in theoretical applied mechanics in which I need to find the solution for 5 unknown but I have 6 equations. None of the equations is redundant and I need the solution of the variable to satisfy each of the equations.

These are the equations 

24-52*L^4*m[0]*Omega^2*(R+1/2)/EI[0]-168*beta[1]-52*F*L^2/EI[0]+104*beta[2]+(120+72*beta[1]+104*L^4*m[0]*Omega^2*R/EI[0]-504*beta[2]+312*beta[3]+84*L^4*m[0]*Omega^2*(R+1/2)/EI[0...

[24+24*beta[1]*x+24*beta[2]*x^2+24*beta[3]*x^3+24*beta[4]*x^4]+(2*[[beta[1]+2*beta[2]*x+3*beta[3]*x^2+4*beta[4]*x^3]])*(-24+24*x)+[2*beta[2]+6*beta[3]*x+12*beta[4]*x^2]*(12-24*x+12*x^2)-L^4*m[0]*Omega^2*[-(1/2)*x^2-R*x+R+1/2]*(12-24*x+12*x^2)/EI[0]-F*L^2*(12-24*x+12*x^2)/EI[0]-L^4*m[0]*Omega^2*[-x-R]*(12*x-12*x^2+4*x^3)/EI[0]-L^4*m[0]*omega^2*(6*x^2-4*x^3+x^4)/EI[0]

 

This is the result of a mathematical procedure. I need to be able to extract the series...

Regards,

I need help with solving an equation. I have the following equation:

24*b[0]+24*b[1]*xi+24*b[2]*xi^2+(2*(-12+24*xi))*(b[1]+2*b[2]*xi)+(2*(-12*xi+12*xi^2))*b[2]+P[cl]*L^2*(-12*xi+12*xi^2)

to this equation I applied the comand: series(%,xi) and as a result obtained:

24*b[0]-24*b[1]+(72*b[1]-72*b[2]-12*P[cl]*L^2)*xi+(144*b[2]+12*P[cl]*L^2)*xi^2

My question is: the way to solve this equation in the manner I need is setting the coefficients...

Regards, I have a question about the solve function in maple

How does the solve function works?

I know if you have a random eq lets say y:= x-> x^2 + 5 x

and I use the function like....   solve(x^2+5x = 8) it will solve it for me giving me numerical values for x or the roots of x

If I have an eq w(x) and it has constants lets say w:= x -> a[1]x^2+a[2]x^4

and i solve this equation in this manner:    solve([w(0),w(1),D(w)(0),D(w)(1)])

Regards, I am conducting independent research in my university and I was recomended to use this software but since I am more familiar with matlab it feels harder to use maple and I'm making many mistakes.

My question is how to solve the following equation w(xi) = a_0 + a_1 * xi + a_2 * xi^2 + a_3 * xi^3 + a_4 * xi^4

So I defined xi = x/L

and gave some boundary/initial conditions for this equation(don't know if this is right)

w(0) = 0 : w(L...
