New issue 1872 by carlosgs91: I want to help http://code.google.com/p/sympy/issues/detail?id=1872 Hi, I don't know where else can I post this. I'm using sympy in my ipod Touch and it's really cool. I'm doing new functions and doing them shorter for the iPhone and I'd like to share with you this new functions I'm creating, so I would like yo join the team. Right now I'm working trying to do a taylor function for 2 variables. I've also done another taylor function that allows you to select the grade of taylor. Anyway, till now I've written all this: def sym(val): return Symbol(val) def uin(f,v): return integrate(f,v) def din(f,v,a,b): endint=integrate(f,v).subs(v,b) startint=integrate(f,v).subs(v,a) res=endint-startint-0.1+0.1 return res def pp(f): return pprint(f) def ud(f,v): return diff(f,v) def dd(f,v,a): ddiff=diff(f,v).subs(v,a) res=ddiff-0.1+0.1 return res def mud(f,v,d): mul = f for i in range(0,d): mul = ud(mul,v) return mul def mdd(f,v,d,p): mul = f for i in range(0,d): mul = ud(mul,v) return mul.subs(v,p) def fa(n): return factorial(n) def ta(f,v,p,d): u = f.subs(v,p) for i in range(1,d+1): u = u + (mdd(f,v,i,p)*((x-p)**i))/fa(i) return u def dot(u,v): r = 0 for i in range(0,len(u)): r = r + u[i]*v[i] return r def vsum(u,v): r = [] for i in range(0,len(u)): a = 0 a = u[i]+v[i] r.append(a) return r def vmin(u,v): r = [] for i in range(0,len(u)): a = 0 a = u[i]-v[i] r.append(a) return r -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
