lim x->0 sin2x/sin3x Free Math Help Forum

WebFeb 18, 2016 · still didn't understand the solution i.e. if we substitute 1 for sin2x/2x and sin3x/3x we are left with the 2x/3x - how is that supposed to be = 1 /what is the thinking behind this ? Is it that as x->0, 2x and 3x are approx the same and therefore 2x/3x approx 1 ? ***** Proof: special limit is that lim as x->0 (sinA/A) = 1 So sin2x/(2x) = 1 WebJul 30, 2024 · Best answer lim x→0 tan 3x sin 4x lim x → 0 t a n 3 x s i n 4 x lim (x→0) tan 3x/sin 4x To Find: Limits NOTE: First Check the form of imit.
