Question

How to prepare a integral for odesolve

Hi guys,

I have a problem with an integral that I would like to link in the solve block using odesolve.

The Integral (sin A(s) ds) can't be written in the solve block or the solution can't be found. I tried to rewrite the integral in a sum or I tried to use the trapezoidel rule, but it doesn't work either.

 

A(s) isn't given, but dA(s)/ds will be solved during the solution.

 

I am looking forward to your helpfull answers 😉

 

Best regards

David

odesolve will not deal with integral equations.

 

Can you take the derivative of your equation to eliminate the integral?

    I tried that last week and it doesn't work. Today I tried the same way an it works. Thank you very much.

    As Fred says, odesolve doesn't solve integral equations. To comment beyond that, we would need to see a worksheet.
