limit as x approaches-1 of cos(2pix-pi)

x \to - 1 lim (cos (2 π x - π))

- 1

Solution steps

x \to - 1 lim (cos (2 π x - π))

Plug in the value

x = - 1

= cos (2 π (- 1) - π)

Simplify

cos (2 π (- 1) - π) : - 1

= - 1

x \to \infty lim (x^{2} - 6 x)

x \to π lim (x - π)

x \to - 1 + lim (5 x^{3} + 2)

x \to 0 lim (\frac{( x - 2 ) ^{3} + 8}{x})

x \to 0 lim (\frac{x}{ln ( 2 x )})
