I'm a little confused with the .series method. In [8]: sin(x).series(x,0,10) Out[8]: 3 5 7 9 x x x x x - ── + ─── - ──── + ────── + O(x**10) 6 120 5040 362880
In [9]: cos(x).series(x,0,10) Out[9]: 2 4 6 8 x x x x 1 - ── + ── - ─── + ───── + O(x**10) 2 24 720 40320 >From this it seems that .series(x,point,n) calculates the series expansion of f(x) till the nth exponent of x... But, In [17]: exp(x**2).series(x,0,10) Out[17]: 4 6 8 10 12 14 16 18 2 x x x x x x x x 1 + x + ── + ── + ── + ─── + ─── + ──── + ───── + ────── + O(x**20) 2 6 24 120 720 5040 40320 362880 This doesnt seem to match up... Does the parameter 'n' mean 'the no of terms in the series expansion' or ' the last exponent of x in the expansion' ? -- You received this message because you are subscribed to the Google Groups "sympy" group.
