lim_(x→0)  ((sin 2x+p sin x)/x^3 ) = q . where q finite

lim_(x→0)  (((2x−((8x^3 )/6))+p(x−(x^3 /6)))/x^3 ) = q  since q finite , so 2+p = 0 , p=−2  now we can find q  lim_(x→0) ((−((9/6))x^3 )/x^3 ) = q ⇒q = −(3/2)  ∴  { ((p = −2)),((q = −(3/2))) :}
limx0(2x8x36)+p(xx36)x3=qsinceqfinite,so2+p=0,p=2nowwecanfindqlimx0(96)x3x3=qq=32{p=2q=32
