limit as x approaches pi/4 of cot(x)

x \to \frac{π}{4} lim (cot (x))

1

Solution steps

x \to \frac{π}{4} lim (cot (x))

Plug in the value

x = \frac{π}{4}

= cot (\frac{π}{4})

Use the following trivial identity:

cot (\frac{π}{4}) = 1

cot (x)

periodicity table with

πn

cycle:

x 0 \frac{π}{6} \frac{π}{4} \frac{π}{3} \frac{π}{2} \frac{2 π}{3} \frac{3 π}{4} \frac{5 π}{6} cot (x) \mp \infty 31 \frac{3}{3} 0 - \frac{3}{3} - 1 - 3

= 1

\int_{0}^{\frac{π}{2}} tan (x) d x

\int \frac{1000 x}{x ^{2} + e} d x

(x^{2} - 8 x + 4) 25 - x^{2}

x \to 0 lim (\frac{3 ∣ x ∣}{x})

\int (x^{4} ln (x)) d x
