limit as x approaches 1 of cos(2x)

x \to 1 lim (cos (2 x))

cos (2)

Decimal

- 0.41614 \dots

Solution steps

x \to 1 lim (cos (2 x))

Plug in the value

x = 1

= cos (2 \cdot 1)

Simplify

= cos (2)

x \to 2 lim (8 - 3 x)

x \to π lim (10 sin (x))

x \to 2 + lim (e^{x - 2})

x \to \infty lim (\frac{( - 2 ) x ^{3} + x ^{2} + 1}{( - 3 ) x ^{4} + 2 x ^{2} + 1})

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