In a "If" conditional statement, maple returns

Error, cannot determine if this expression is true or false: 1.551691464 < (5/6)*Pi

I want to find the parameters m to the equation x^4 -(3*m+2)*x^2 + 3*m+3 = 0 has four distinct solutions and all of them were less than 2. I tried

eq:= x^4 -(3*m+2)*x^2 + 3*m+3:

sol:=[solve(eq=0,x)]:

d:=discrim(eq,x):

solve([d>0,sol[1]<2,sol[2]<2,sol[3]<2,sol[4]<2],m):

allvalues(%);

How to reduce my code?

I am not sure if this is a general problem. And I am considering the best way to evaluate the expression (Equation) when it contains variables which have been modified by using assume. Here is a tiny test example:

restart;assume(a>0,x>0);int(int(x^2/y^2,y=1/x..x),x=1..a);S:=%: 1 4 1 1 2

Dear All:

I met an strange problem when using fsolve() function in maple. the following is my system equations, ILr0,Vcr0,M,T1 is the values i need to solved by maple .

ILr2+ILr0=0,Vcr0+Vcr2=0,ILr1=ILm1,Iout*RL=Vout (1) where

ILr2--> ILr0*f1(T1)+Vcr0*f2(T1)+M*f3(T1);

Vcr2--> ILr0*g1(T1)+Vcr0*g2(T1)+M*g3(T1);

ILr1,ILm1--> ILr0*h1(T1)+Vcr0*h2(T1)+M*h3(T1);

Hi there,

Unfortunately I don't have access to Maple because I am away from my office for the week, but I need a

system of linear equations solved. Can someone please solve it for me and post the solutions (if any)?

The system is:

a_1 x_1 + b_1 x_2 + c_1 x_3 + d_1 x_4 = e_1 + e_4

a_2 x_1 + b_2 x_2 + c_2 x_3 + d_2 x_4 = e_2

a_3 x_1 + b_3 x_2 + c_3 x_3 + d_3 x_4 = 0

a_4 x_1 + b_4 x_2 + c_4 x_3 + d_4 x_4 = e_1 + e_4

Hi,

I'm searching for the third differential equation that will transform the following two equations non-autonomous system into a three equations autonomous one:

diff(x(t),t)=-x(t)+2*(m*t+n)*y(t)-2*k*(m*t+n)^{2}

diff(y(t),t)=-y(t)+k*m-(m*t+n)*((x(t)/2)-1)

diff(z(t),t)= ...

Regards,

Johnny

Hello, im a current user of Maple 16, i have a problem in finding a minimum of equation ( equation of a external work equating the internal energy dissipation) f= E-W ( im studying a slope stability with limit analysis)

the equation is:

I have total nine equations,out of which some are linear and some of them are nonlinear.I am a new user of maple.The nine equations are

c2+vc = .34,

c2+c3 = .519,

t8+c3-c4-vc = .132,

t1+t5-c2+0.0435=0,

t1-t2-c2+c3-1.334*vc = 0,

t2+t6-c3-c4+0.0435+1.334*vc=0,

-112.5*t1+112.5*t5+300*c2^2+1000*vc = 38.25,

112.5*t1-112.5*t2-300*c2^2+300*c3-300*c3^2-2000*vc+23.4 = 0,

-112.8*t8+112.5*t2-112.5*t6+300*c4^2-300*c3+300*c3^2+1000*vc+14.85 = 0

Many times when I use dsolve to find the solution of an equation like x-y/y' = y , I get a term involving the LambertW function. However, the equation has homogeneous coefficients for dx and dy, so it can easily be solved by substituting y=u*x and separating the variables. The closed form solution of the above is x+y*ln(y)+c*y = 0 , but I cannot get that answer from Maple. Is there...

Hello!

It seems there's some problems with spaces in the name of equation

As you can see the 'SOLVE' command can't substitute variable 'b' in my example, if 'b' variable wasn't defined BEFORE the equation with spaces in its name....
