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

x \to \frac{π}{2} lim (2 cos (x))

0

Solution steps

x \to \frac{π}{2} lim (2 cos (x))

Plug in the value

x = \frac{π}{2}

= 2 cos (\frac{π}{2})

Simplify

2 cos (\frac{π}{2}) : 0

= 0

h \to 0 lim ((1 + 4 h)^{\frac{1}{h}})

x \to 3 lim (\frac{e ^{x} - 1}{x})

x \to 0 lim (+ (x e^{\frac{1}{x}}))

x \to \infty lim ((x)^{0})

x \to 0 - lim (csch (x))
