lim mendekati 1 sin^2 (x-1) / x^2 -2x+1 = UN/2013 mohon bantuannya thx..

[tex]lim \: \frac{ \sin {}^{2} (x - 1) }{x ^{2} - 2x + 1 } \\ = \ \frac{ \sin(x - 1) \times \sin(x - 1) }{ x {}^{2} - 2x + 1 } \\ = \frac{ \sin \: x^{2} + 1 }{x {}^{2} - 2x + 1} \\ = \frac{1}{2x} \\ = \frac{1}{2(1)} \\ = \frac{1}{2} [/tex]
