Oo in the code represents infinity.

From sympy Import *n = Symbol (' n ') s = ((n+3)/(n+2)) **nprint limit (s, N, oo)

The integrate function is used for integral problems.

From sympy Import *t = symbol (' t ') x = symbol (' x ') m = integrate (sin (t)/(PI-T), (t, 0, x)) n = Integrate (M, (x, 0, pi)) print n
