limit as x approaches 0 of x^2csc^2(x)

x \to 0 lim (x^{2} csc^{2} (x))

1

Solution steps

x \to 0 lim (x^{2} csc^{2} (x))

Rewrite for L'Hopital

= x \to 0 lim (\frac{x ^{2}}{\frac{1}{c s c ^{2} ( x )}})

Apply L'Hopital's Rule

: x \to 0 lim (\frac{2 x}{sin ( 2 x )})

= x \to 0 lim (\frac{2 x}{sin ( 2 x )})

Apply L'Hopital's Rule

: x \to 0 lim (\frac{2}{cos ( 2 x ) \cdot 2})

= x \to 0 lim (\frac{2}{cos ( 2 x ) \cdot 2})

Plug in the value

x = 0

= \frac{2}{cos ( 2 \cdot 0 ) \cdot 2}

Simplify

\frac{2}{cos ( 2 \cdot 0 ) \cdot 2} : 1

= 1

\frac{d}{d x} (tan (x) - x + 1)

\frac{d}{d x} (1 + x^{256} - 1)

y^{^{''}} - 6 y^{^{'}} = 9 t

f (x) = 19 x e^{x}

\int sin (x) e^{3 x} d x
