limit as x approaches 0+of cot(x)-csc(x)

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

0

Solution steps

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

Multiply by the conjugate of

cot (x) - csc (x) : \frac{- 1}{cot ( x ) + csc ( x )}

= x \to 0 + lim (\frac{- 1}{cot ( x ) + csc ( x )})

x \to a lim [c \cdot f (x)] = c \cdot x \to a lim f (x)

= - x \to 0 + lim (\frac{1}{cot ( x ) + csc ( x )})

x \to a lim [\frac{f ( x )}{g ( x )}] = \frac{lim _{x \to a} f ( x )}{lim _{x \to a} g ( x )}, x \to a lim g (x) \neq = 0

With the exception of indeterminate form

= - \frac{lim _{x \to 0 +} ( 1 )}{lim _{x \to 0 +} ( cot ( x ) + csc ( x ) )}

x \to 0 + lim (1) = 1

x \to 0 + lim (cot (x) + csc (x)) = \infty

= - \frac{1}{\infty}

Apply Infinity Property:

\frac{c}{\infty} = 0

= 0

\int sec (y) tan (y) d y

\frac{d}{d x} (\frac{1}{x + 7})

\int x^{2} x + 22 d x

x \to 0 lim (a x + b)

\int_{0}^{10} e^{x} sin (x) d x
