derivative of ODE
Publié : mer. sept. 21, 2016 2:41 pm
Is there a way to differentiate or integrate ODEs?
For example:
d/dt(1/2*m*(d2/d2t(x))^2+1/2*k*x^2)
where d2/d2t(x) is the second derivative of x w/respect to t and d/dt represents taking the derivative (which I would like to do in xcas)
I hope this is clear.
I should get:
m*d/dt(x)*d2/d2t(x)+k*x*d/dt(x)
For example:
d/dt(1/2*m*(d2/d2t(x))^2+1/2*k*x^2)
where d2/d2t(x) is the second derivative of x w/respect to t and d/dt represents taking the derivative (which I would like to do in xcas)
I hope this is clear.
I should get:
m*d/dt(x)*d2/d2t(x)+k*x*d/dt(x)
