limit as x approaches 1 of cos(xpi)

x \to 1 lim (cos (x π))

- 1

Solution steps

x \to 1 lim (cos (x π))

Plug in the value

x = 1

= cos (1 π)

Simplify

cos (1 π) : - 1

= - 1

\frac{1}{x ^{13}}

x y^{^{'}} - 2 y = - 2 x^{2} + x - 2

f (x) = 6 x^{2} - x^{3}, at x = 1

- sin (x) - 4

\int (t) (e^{2 t}) d t
