limit as x approaches 0 of xcot(3/5 x)

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

\frac{5}{3}

Decimal Notation

1.66666 \dots

Solution steps

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

Rewrite for L'Hopital

= x \to 0 lim \frac{x}{\frac{1}{c o t ( \frac{3}{5} x )}}

Apply L'Hopital's Rule

: x \to 0 lim (\frac{1}{sec ^{2} ( \frac{3 x}{5} ) \frac{3}{5}})

= x \to 0 lim (\frac{1}{sec ^{2} ( \frac{3 x}{5} ) \frac{3}{5}})

Plug in the value

x = 0

= \frac{1}{sec ^{2} ( \frac{3 \cdot 0}{5} ) \frac{3}{5}}

Simplify

\frac{1}{sec ^{2} ( \frac{3 \cdot 0}{5} ) \frac{3}{5}} : \frac{5}{3}

= \frac{5}{3}

\frac{d}{d x} (sin (arccos (x)))

y^{^{''}} - y^{^{'}} + y = 4 sin (t)

\frac{\partial}{\partial x} (x^{2} e^{3 x} y + \frac{e ^{3 x} y ^{3}}{3})

\int cos^{3} (π x) d x

f (x) = \frac{1}{13 x ^{2}} + \frac{1}{11 x}
