Question

Вычислите значение предела
$lim_{x to 0} frac{sin 3x-2sin 5x}{2sinx}$

Answer 1

$limlimits _{x to 0}dfrac{sin3x-2sin5x}{2sinx}=limlimits _{x to 0}dfrac{sin3x}{2sinx}-limlimits _{x to 0}dfrac{2sin5x}{2sinx}=\\\star ; ; sin, alpha (x)sim alpha (x); ,; esli; alpha (x)to 0; ; star \\=limlimits _{x to$
