limit as x approaches pi/2+of cos(x)

x \to \frac{π}{2} + lim (cos (x))

0

Solution steps

x \to \frac{π}{2} + lim (cos (x))

Plug in the value

x = \frac{π}{2}

= cos (\frac{π}{2})

Use the following trivial identity:

cos (\frac{π}{2}) = 0

cos (x)

periodicity table with

2 πn

cycle:

\int (\frac{4}{x} - 1) d x

\frac{\partial}{\partial x} (x sin (4 x^{2} y))
