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

x \to \frac{π}{4} lim (cot (4 x))

diverges

Solution steps

x \to \frac{π}{4} lim (cot (4 x))

x \to a - lim f (x) \neq = x \to a + lim f (x)

then the limit does not exist

x \to \frac{π}{4} + lim (cot (4 x)) = \infty

x \to \frac{π}{4} - lim (cot (4 x)) = - \infty

= diverges

n = 0 \sum \infty sin (2 n)

\frac{x + x}{x ^{2}}

\frac{\partial}{\partial x} (4 x ln (x y))

\int x^{11} d x

y^{^{''}} + 4 y = 1
