Hello, I tried to solve this equation of degree but it gives me errors
$\dfrac{d^{5}y}{dx^{5}}+5\dfrac{d^{4}y}{dx^{4}}-2\dfrac{d^{3}y}{dx^{3}}-10\dfrac{d^{2}y}{dx^{2}}+\dfrac{dy}{dx}+5y=0$
x = var('x')
y = function('y')(x)
ED = diff(y,x,5)+5diff(y,x,4)-2diff(y,x,3)-10diff(y,x,2)+diff(y,x)+5y == 0
desolve(ED,y,contrib_ode=true).show()
The error is:
NotImplementedError Traceback (most recent call last) <ipython-input-9-c048996b444c> in <module>() 2 y = function('y')(x) 3 ED = diff(y,x,Integer(5))+Integer(5)diff(y,x,Integer(4))-Integer(2)diff(y,x,Integer(3))-Integer(10)diff(y,x,Integer(2))+diff(y,x)+Integer(5)y == Integer(0) ----> 4 desolve(ED,y,contrib_ode=true).show()

how can I solve that? thanks
