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})

Simplify

- cos (\frac{π}{2}) : 0

= 0

d er i v a t i v e y = \frac{6 x ^{2} + 6 x + 2}{x}

d er i v a t i v e 5 cos (x)

\frac{\partial}{\partial x} (x ln (t))

d er i v a t i v e e^{x} - e^{- x}

\int sin (x) \cdot x d x
