Hello. I need to create a function: Pplus(i,t) = t**i * summation((-1)**(i+j)*binomCoeff(i,j)*Pval(j),(j,0,i))
After which I need to define a function: P(t)=summation(Pplus(i,t),(i,0,n)) After which I'll need to do: sqareaP=integrate(P(t)**2,(t,0,1)) I am wondering whether for this I should define Python functions using def Pplus(i,t) and def P(t) or I should define symbolic functions using lambdify and implemented_function. Sorry if I sound lost, because I *am* lost -- I am not yet able to figure out the SymPy way of doing things. -- Shriramana Sharma -- You received this message because you are subscribed to the Google Groups "sympy" group.
