limit as x approaches pi/2 of cot(x)

x \to \frac{π}{2} lim (cot (x))

0

Solution steps

x \to \frac{π}{2} lim (cot (x))

Plug in the value

x = \frac{π}{2}

= cot (\frac{π}{2})

Use the following trivial identity:

cot (\frac{π}{2}) = 0

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

= 0

n = 5 \sum \infty \frac{1}{2 ^{n}}

\frac{d}{d x} (7 x^{2} ln (x))

x^{3} + y^{3} - 3 x^{2} y^{2} + 1

y^{^{''}} + y^{^{'}} - 2 y = 2 t

\int_{0}^{3} x^{2} d x
