limit as x approaches pi of (x-pi)csc(x)

x \to π lim ((x - π) csc (x))

- 1

Solution steps

x \to π lim ((x - π) csc (x))

Rewrite for L'Hopital

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

Apply L'Hopital's Rule

: x \to π lim (\frac{1}{cos ( x )})

= x \to π lim (\frac{1}{cos ( x )})

Plug in the value

x = π

= \frac{1}{cos ( π )}

Simplify

\frac{1}{cos ( π )} : - 1

= - 1

e^{x} \frac{y d y}{d x} = e^{- y} + e^{- 2 x - y}

f (x) = - \frac{1}{( x - 1 ) ^{2}}

(1 - x^{2}) y^{^{''}} + 2 x y^{^{'}} = 0

\int \frac{x}{7 x - 6} d x

\frac{d}{d x} (1 - x^{4})
