limit as x approaches 0-of xcsc(x)

x \to 0 - lim (x csc (x))

1

Solution steps

x \to 0 - lim (x csc (x))

Rewrite for L'Hopital

= x \to 0 - lim (\frac{x}{\frac{1}{c s c ( x )}})

Apply L'Hopital's Rule

: x \to 0 - lim (\frac{1}{cos ( x )})

= x \to 0 - lim (\frac{1}{cos ( x )})

Plug in the value

x = 0

= \frac{1}{cos ( 0 )}

Simplify

\frac{1}{cos ( 0 )} : 1

= 1

\frac{d ^{2}}{d x ^{2}} (cos (- 2 x))

\frac{d}{d x} (cos (x^{2} + π))

g (t) = 2^{t}

x^{2} e^{x - 1}, at 1

\int cot (19 x) d x
