limit as x approaches 0 of (arcsin(5x))/(sin(3x))

x \to 0 lim (\frac{arcsin ( 5 x )}{sin ( 3 x )})

\frac{5}{3}

Decimal Notation

1.66666 \dots

Solution steps

x \to 0 lim (\frac{arcsin ( 5 x )}{sin ( 3 x )})

Apply L'Hopital's Rule

: x \to 0 lim (\frac{\frac{5}{1 - 25 x ^{2}}}{cos ( 3 x ) \cdot 3})

= x \to 0 lim (\frac{\frac{5}{1 - 25 x ^{2}}}{cos ( 3 x ) \cdot 3})

Plug in the value

x = 0

= \frac{\frac{5}{1 - 25 \cdot 0 ^{2}}}{cos ( 3 \cdot 0 ) \cdot 3}

Simplify

\frac{\frac{5}{1 - 25 \cdot 0 ^{2}}}{cos ( 3 \cdot 0 ) \cdot 3} : \frac{5}{3}

= \frac{5}{3}

x \to \infty lim (x^{2} + 2 x - x^{2} + (2 + 4) x)

x \to \infty lim (5 x - 2)

h \to 0 lim (\frac{3 h}{h})

x \to \infty lim (\frac{3 x + 1}{2 x + 1})

x \to 7 - lim (\frac{2}{x - 7})
