limit as x approaches 0 of ((x-tan(3x)))/((x+tan(2x)))

x \to 0 lim (\frac{( x - tan ( 3 x ) )}{( x + tan ( 2 x ) )})

- \frac{2}{3}

Decimal

- 0.66666 \dots

Solution steps

x \to 0 lim (\frac{x - tan ( 3 x )}{x + tan ( 2 x )})

Divide by highest denominator power:

\frac{1 - \frac{t a n ( 3 x )}{x}}{1 + \frac{t a n ( 2 x )}{x}}

= x \to 0 lim (\frac{1 - \frac{t a n ( 3 x )}{x}}{1 + \frac{t a n ( 2 x )}{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 - \frac{t a n ( 3 x )}{x} )}{lim _{x \to 0} ( 1 + \frac{t a n ( 2 x )}{x} )}

x \to 0 lim (1 - \frac{tan ( 3 x )}{x}) = - 2

x \to 0 lim (1 + \frac{tan ( 2 x )}{x}) = 3

= \frac{- 2}{3}

Simplify

= - \frac{2}{3}
