Exactly

x is the only variable. a and b are real constants. you have to read x*a and x*b and not xa and x[SUB]b

A1*(tan(xa/alfa2)/tan(xa/alfa1))-tan(xa/alfa2)*tan(xb/alfa2)-A1*(tan(xb/alfa2)/tan(xa/alfa1))=1 thanks again

Hi everybody, can anyone help me in finding the analytic solution of the trascendental equation in the attached file? A1, alfa1, alfa2, a and b are constants. is it possible to solve it by means of Mathematica? thanks Michele

i have found in literature the Chini equation, which is similar to the equation I'm trying to solve. unfortunately i can't found the solution. can everyone help me, please?

the DE is right...the BERNOULLI equation is homogeneous and I actually can't tarnsform my equation in a Bernoulli one. can you suggest me how to transform it?

the mentioned equation is the result of the integration of the heat diffusion eqaution following the approximate integral method. is it possible to use any methods to linearize this equation?

Hi everybody, could anyone help me in the linearization of the following non linear non-homogeneous ODE? A*dy/dt+B*y^(4)=C where A, B and C are constants. y is a function of t. is it possible to reduce this equation to a Riccati equation? do you know any analytical, approximate or...

dear friends, i need to solve analitically(also by means of approximate methods) the following nonlinear differential equation: (A+BTs^(3))*dTs/dt+C*Ts^(4)=D where Ts is a function of t. A, B, C and D are costants. the initial condition is Ts(0)=Ti. I would be so grateful if anyone can...
