limit as x approaches 3 of (sin(3x))/x

x \to 3 lim (\frac{sin ( 3 x )}{x})

\frac{1}{3} sin (9)

Decimal

0.13737 \dots

Solution steps

x \to 3 lim (\frac{sin ( 3 x )}{x})

Plug in the value

x = 3

= \frac{sin ( 3 \cdot 3 )}{3}

Simplify

\frac{sin ( 3 \cdot 3 )}{3} : \frac{1}{3} sin (9)

= \frac{1}{3} sin (9)

x \to 4 lim (x + x - 4)

\int \frac{x}{( x ^{2} + 6 ) ^{2}} d x

\frac{d y}{d t} - 4 y = 2 e^{5 t}

\frac{\partial}{\partial x} (3 e^{s i n (x + 4 c t)})

\frac{\frac{1}{s + 1} - 1}{s ^{2} + 1}
