Penjelasan:

#lim_ (x-> 0) (sin ^ 2x) / x #

----#lim_ (x-> 0) (sinx) / x = 1 #

berganda dengan

#lim_ (x-> 0) (sinx.sinx) / x = lim_ (x-> 0) (x) / x (sinx.sinx) / x #

(x-> 0) (x) / x (sinx.sinx) / x = lim_ (x-> 0) x ((sinx.sinx)) / (xx) = lim_ (x-> 0) / x) (sinx / x) (x) #

#lim_ (x-> 0) (sinx / x) (sinx / x) (x) = 1.1.x = x #

#lim_ (x-> 0) (sin ^ 2x) / x = lim_ (x-> 0) x #

#lim_ (x-> 0) x = 0 #
