Hi every one.
can any one help me to solve this equations in mathematica?
Thank you
y1(x)=B1e(-ibx)+C1e(bx)
y2(x)=A2e(ibx)+D2e(-bx)
1:y1(0)=y2(0)
2:y1’(0)=y2’(0)
3:y1’‘(0)=y2’‘(0)
4:y1’‘’(0)-y2’‘’(0)=1/EJ
EJ= constant value
we should find B1,C1,A2 and D2 while all the conditions are satisfied.
Thank you
… while all the conditions are satisfied.
The first condition is to bring the problem in a form it can be treated with Mathematica. Did you try anything?
I tried to solve but I could not define 4 conditions to solve.
This looks like a homework problem.
You have shown the four equations, but you haven’t shown how to use Mathematica to find each of those four exactly.
Do that first.
Then look up Reduce or Solve in the documentation.
That should be enough of a hint.
